The  completion  of  the  fourth  Tolnme  of  the  Catalogue  of  Tossil 
Pishes  preserved  in  the  Geological  Department  of  the  British 
Museum  of  Natural  History  will  afford  much  satisfaction  to 
palaeontologists — more  especially  to  those  who  are  interested  in 
the  study  of  Ichthyology.  Nor  can  it  be  deemed  inappropriate  to 
congratulate  the  author,  Dr.  Arthur  Smith  Woodward,  P.B.S.,  upon 
the  consummation  of  a  task  which  has  extended  over  at  least 
17  years,  during  which  time  a  very  large  amount  of  other  scientific 
work  has  been  accomplished  by  him.  Indeed,  the  present  volume 
would  have  appeared  early  in  the  Spring,  but  was  delayed  in  con¬ 
sequence  of  the  author’s  absence  for  three  months  in  Greece, 
where  he  was  engaged  in  carrying  out  for  the  Museum  the 
exploration  of  the  Tertiary  Mammalian  deposits  at  Pikermi  near 
Athens. 

Dr.  Smith  Woodward  proposes  to  prepare,  in  1902,  a  Supplement 
giving  a  list  of  additional  important  genera  discovered  and  published 
since  the  earlier  volumes  appeared;  also  a  Stratigraphical  Table 
showing  the  appearance  in  time  of  families  and  genera  of  Dossil 
Fishes ;  together  with  a  General  Index  to  the  four  volumes ;  the 
4th  volume  being  already  larger  than  its  predecessors,  and  the 
illustrations  more  numerous. 

It  is  probable  that  the  Collection  of  Fossil  Fishes  is  the  largest 
in  the  world,  the  English  Cretaceous  Fishes  being  particularly  rich.

INTRODUCTION. 


As  soon  as  fishes  with  a  completely  osseous  endoskeleton  began  to 
predominate  at  the  dawn  of  the  Cretaceous  period,  specialisations 
of  an  entirely  new  kind  were  rapidly  acquired.  Until  this  time 
the  skull  of  the  Actinopterygii  had  always  been  remarkably 
uniform  in  type.  The  otic  region  of  the  cranium  often  remained 
incompletely  ossified,  and  was  never  prominent  or  projecting  beyond 
the  roof-bones ;  the  supra-occipital  bone  was  always  small  and 
covered  with  the  superficial  plates  ;  the  maxilla  invariably  formed 
the  greater  part  of  the  upper  jaw  ;  the  cheek-plates  were  large  and 
usually  thick ;  while  none  of  the  head  or  opercular  bones  were 
provided  with  spines  or  ridges.  The  pelvic  fins  always  retained 
their  primitive  remote  situation,  and  the  fin-rays  never  became 
spines.  During  the  Cretaceous  period  the  majority  of  the  bony 
fishes  began  to  exhibit  modifications  in  all  these  characters,  and 
the  changes  occurred  so  rapidly  that,  by  the  dawn  of  the  Eocene 
period,  the  diversity  observable  in  the  dominant  fish-fauna  was 
much  greater  than  it  had  ever  been  before.  At  this  remote  epoch, 
indeed,  nearly  all  the  great  groups  of  bony  fishes,  as  represented 
in  the  existing  world,  were  already  differentiated,  and  their 
subsequent  modifications  have  been  quite  of  a  minor  character. 

It  is  the  object  of  the  present  volume  to  enumerate  and  partially 
discuss  the  known  Cretaceous  and  Tertiary  bony  fishes  which 
illustrate  these  phenomena.  The  result,  however,  is  much  less 
satisfactory  than  might  have  been  expected  from  the  study  of 
animals  which  lived  under  conditions  most  favourable  for  their 
preservation  as  fossils.  The  circumstance  that  a  very  large  pro¬ 
portion  of  the  Tertiary  fishes  are  known  only  from  detached 
otoliths,  suffices  to  indicate  the  extreme  imperfection  of  the 
geological  record  in  their  case.

INTEODUCTIOIS'. 


ISOSPONDTLI. 

The  most  important  Cretaceous  families  of  primitive  bony  fishes 
are  the  Elopidse  and  Chirocentridne,  which  have  a  few  Tertiary 
representatives,  but  are  almost  extinct  at  the  j)resent  day.  Their 
distribution  in  the  seas  of  the  Cretaceous  period  is  known  to  have 
been  very  wide,  and  individuals  of  the  various  species  were 
especially  abundant. 

The  Elopidae,  represented  in  the  existing  fauna  by  Flops  and 
Megalops^  cannot  be  the  direct  descendants  of  the  Jurassic  Lepto- 
lepidae,  because  all  the  satisfactorily-known  genera  still  retain  the 
gular  plate.  This  plate,  however,  now  appears  for  the  last  time  in 
the  class  of  fishes,  being  completely  absent  in  all  known  repre¬ 
sentatives  of  the  higher  grades ;  and  in  some  of  the  Elopines 
themselves,  such  as  Thrissopater  (p.  33,  no.  9052)  and  Spaniodon 
(p.  51,  no.  P.  9190),  it  is  quite  a  rudimentary  structure.  The  skull 
still  differs  very  little  from  that  of  the  higher  Jurassic  fishes,  and 
the  otic  region  remains  covered  by  the  roof-bones.  In  the  Elopidse, 
however,  the  supraoccipital  bone  begins  for  the  first  time  to  exhibit 
the  forward  and  upward  growth  which  characterises  it  in  all  the 
higher  bony  fishes.  The  parietal  bones  still  meet  in  the  middle 
line  in  several  of  the  genera;  but  even  in  this  case  the  supra¬ 
occipital  may  extend  forwards  beneath  them  to  meet  the  frontals 
(e.  g.  Megalops,  p.  24).  In  some  early  genera  they  are  distinctly 
separated  in  the  cranial  roof  by  the  exposure  of  the  supraoccipital. 
In  this  family,  therefore,  the  latter  element  exhibits  the  usual 
inconstancy  of  an  incipient  or  developing  structure. 

The  Albulidse  are  merely  Elopiue  fishes  with  a  forwardly-inclined 
mandibular  suspensorium,  a  small  mouth,  and  reduced  branchio- 
stegal  apparatus.  Their  primitive  character  is,  indeed,  shown  by 
the  presence  of  a  muscular  conns  arteriosus  with  two  rows  of 
valves  in  the  heart  of  the  sole  surviving  species  h  They  seem  to 
differ  from  the  Elopidae  in  exactly  the  same  manner  as  the  more 
generalised  Pycnodontidae  differ  from  the  Semionotidae  among 
Jurassic  fishes.  Now,  however,  the  splenial  bone  has  disappeared 
and  is  no  longer  available  to  bear  a  powerful  dentition.  A  new 
modification  therefore  occurs  for  the  first  time,  and  is  almost  con¬ 
stantly  repeated  in  later  fishes  which  have  teeth  on  the  palate  or

the  base  of  the  skull.  This  upper  dentition  is  henceforth  usually 
opposed  not  to  the  mandible  but  to  a  dental  arrangement  on  the 
tongue  or  hyoid  apparatus. 

One  of  the  common  Cretaceous  fishes  (^Istieus,  p  66),  here  placed 
in  the  Albulidae,  is  interesting  as  being  essentially  identical  with 
an  imperfectly-known  fish  still  surviving  in  the  deep  sea  {Batliy- 
thrissa).  It  is  the  most  elongated  type  of  this  primitive  group, 
with  multiplied  vertebrse  and  an  extended  dorsal  fin. 

The  Osteoglossidse,  with  a  curiously-thickened  skull,  also  seem 
to  be  closely  related  to  the  early  Albulidse.  The  fragmentary  fossils 
already  discovered  suggest  that  these  families  will  need  a  new 
definition  as  soon  as  their  extinct  representatives  are  satisfactorily 
known. 

The  primitive  nature  of  the  Chirocentridae  has  long  been  inferred 
from  the  presence  of  a  rudimentary  spiral  valve  in  the  intestine  of 
the  sole  surviving  species,  Chirocentrus  clorab  h  This  family  of 
fishes  is,  indeed,  now  proved  to  be  very  old,  dating  back  at  least  to 
the  beginning  of  the  Cretaceous  period,  during  which  it  attained  its 
maximum  development.  Early  Cretaceous  forms,  such  as  Chiro- 
centrites,  cannot  even  be  distinguished  from  the  typical  species  of  the 
Upper  Jurassic  Thrissops  until  the  cranium  be  available  for  detailed 
study.  It  is  still  not  definitely  determined  that  Thrissops  belongs 
to  the  lower  division  (family  Leptolepidae)  in  which  it  is  usually 
placed. 

The  true  Clupeoid  fishes  also  date  back  to  the  beginning  of  the 
Cretaceous  period,  and  their  skeleton  is  so  closely  similar  to  that  of 
the  typical  Jurassic  Leptolepidae  that  they  may  well  be  direct 
descendants  of  the  latter.  Their  higher  grade  is  definitely  indicated 
by  the  prominence  of  the  supraoccipital  and  otic  bones  in  the  skull. 
Most  of  the  Cretaceous  forms  are  typical  Clupeidae,  and  they  have 
scarcely  changed  during  subsequent  epochs.  A  few,  however,  dis¬ 
covered  only  in  Cretaceous  rocks,  are  of  special  interest  as  exhibiting 
the  precocious  development  of  a  character  which  was  never  per¬ 
manently  acquired  by  fishes  with  so  primitive  a  skull,  but  soon 
became  the  common  feature  of  the  spiny-finned  or  acanthopterygian 
families.  These  are  the  Ctenothrissidae,  which  have  hitherto  been 
mistaken  for  Berycoids  because  they  display  the  character  in 
question,  namely,  the  forward  displacement  of  their  pelvic  fins, 
which  are  situated  more  or  less  directly  beneath  the  pectoral  pair.

IN-TEODTJCTION-. 


The  few  undivided  rays  in  front  of  their  fins,  however,  are  always 
articulated  distally  and  never  form  true  spines. 

Among  the  typical  Cretaceous  Clupeidse  the  early  acquisition  of 
the  ventral  ridge-scutes,  peculiar  to  Clupea  and  its  allies,  is  specially 
noteworthy.  Some  small  fishes  from  the  Neocomianof  Switzerland 
(p.  138)  exhibit  these  scutes  quite  clearly.  A  widespread  marine 
Cretaceous  genus,  Diplomystus^  possessed  dorsal  ridge-scutes  as  well 
as  the  ventral  series.  It  became  a  freshwater  fish  in  the  Eocene 
period,  and  now  survives  only  in  the  rivers  of  New  South  Wales 
and  Chili.  Pectinated  scales  also  characterised  one  Cretaceous 
genus  {Fseiidoberyx),  which  is  proved  to  be  a  Clupeoid — and  not  a 
Berycoid  as  hitherto  supposed — by  the  distinctly  observable  structure 
of  the  head  and  fins. 

Nothing  is  definitely  known  concerning  the  extinct  Salmonoids  ; 
and  Palaeontology  affords  no  information  concerning  the  origin  or 
relationships  of  this  family. 

Of  all  Cretaceous  Isospondyli,  three  families  of  eel-shaped  fishes 
are  the  most  difficult  to  understand.  They  are  all  characterised  by 
a  primitive  cranium  of  the  Jurassic  type ;  but  they  exhibit  the 
new  specialisation  by  which  the  extending  premaxiUa  gradually 
excludes  the  maxilla  from  the  upper  border  of  the  mouth.  Their 
elongated  shape  is  alone  indicative  of  high  specialisation  ;  but  no 
intermediate  forms  are  yet  known  to  afford  a  clue  to  their  more 
normally  shaped  ancestors.  Of  these  families  the  Halosauridse  and 
Notacanthidae  still  survive  in  the  deep  sea.  The  existing  Halo- 
saurus  itself,  indeed,  cannot  be  clearly  distinguished  from  the 
Cretaceous  EcMdnocephalus ;  while  Notacanihus  of  the  present 
fauna  only  seems  to  differ  from  Pronotacanthus  of  the  Cretaceous 
period  in  the  possession  of  dorsal  spines  and  fin-rays.  The  Der- 
cetidag,  on  the  other  hand,  are  only  known  by  fossils  from  Cre¬ 
taceous  formations,  in  which  they  are  widely  distributed.  They 
are  interesting  as  being  the  earliest  type  of  fish  in  which  evidence 
of  a  distensible  stomach  has  been  observed  (p.  177).  Their  fins 
are  less  specialised  than  those  of  the  two  families  just  mentioned  ; 
and  their  trunk  is  provided  with  paired  longitudinal  series  of 
enlarged  scutes. 

Isospondyli  exhibiting  a  definite  tendency  towards  the  develop¬ 
ment  of  acanthopterygian  fishes  seem  to  have  been  almost  as 
abundant  in  Cretaceous  seas  as  the  Elopines  and  Clupeoids.  In 
fact,  in  the  absence  of  a  complete  knowledge  of  the  skeleton,  some 
of  the  Cretaceous  fishes  might  be  referred  equally  well  to  the

Isospondylous  Scopelidse  or  to  the  Acanthopterygian  Berycidae. 
One  very  abundant  family,  that  of  the  Enchodontidae,  might  perhaps 
furnish  the  ancestors  of  both.  These  exclusively  Cretaceous  fishes 
are  Scopeloids,  in  which  the  premaxilla  has  not  completely  excluded 
the  maxilla  from  the  tooth-bearing  margin  of  the  jaw.  They  are 
variously  specialised  by  the  development  of  large  teeth  and  dermal 
scutes ;  and  two  of  them  {EurypJiolih  and  Prionolepis)  are  provided 
with  a  formidable  spine  at  the  angle  of  the  preoperculum — a  feature 
unknown  among  existing  physostomous  fishes.  The  stoutness  of 
their  bones  indicates  that  they  lived  in  shallow  water  or  at  the 
surface  of  the  ocean  during  the  Cretaceous  period;  while  their 
nearest  allies  at  the  present  day — the  Odontostomidae  and  Alepi- 
sauridae — are  all  denizens  of  the  deep  sea. 

Of  the  family  Scopelidae  many  of  the  Cretaceous  representatives 
scarcely  differ  from  genera  widely  distributed  in  existing  seas. 
The  only  remarkable  Cretaceous  forms — and  those  provisionally 
placed  here — are  two  genera  in  which  the  stout  premaxilla  forms 
a  pointed  rostrum.  These  sine  Apateodiis  and  EJiinellus',  the  former 
with  a  short  snout,  the  latter  with  so  slender  a  rostrum  that  a  very 
superficial  study  of  the  fish  has  caused  it  hitherto  to  be  erroneously 
classified  with  Belone  and  the  Scombresocidae. 

The  Gonorhynchidse  are  only  slightly  modified  Scopeloids,  and 
are  now  shown  to  date  back  to  the  Cretaceous  period,  when  all  the 
characteristic  features  of  Gonorhynchus,  except  the  extension  of 
scales  over  the  head,  seem  to  have  been  already  acquired.  The 
discovery  of  an  early  Tertiary  freshwater  genus  {Notogoneus)  both 
in  Korth  America  and  Europe,  is  one  of  considerable  interest. 

Other  modified  Scopeloids  seem  to  be  recognisable  among  Cre¬ 
taceous  fishes,  but  their  osteology  is  as  yet  imperfectly  known. 
The  remarkable  extinct  “  flying  fishes  ”  of  the  family  Chirothricidae 
may  probably  be  thus  interpreted. 

The  Esocidae  are  essentially  freshwater  Scopeloids,  and  the 
Cyprinodontidae  are  generally  admitted  to  be  closely  allied  to  this 
family.  Nothing  of  importance  is  known  concerning  their  geolo¬ 
gical  history. 

OSTAEIOPEYSI. 

The  past  history  of  all  freshwater  fishes  is  very  imperfectly 
known.  Ereshwater  deposits  are  of  such  limited  extent  that  they 
rarely  escape  denudation  for  long  geological  periods ;  and,  except 
perhaps  from  a  few  sediments  deposited  at  the  mouths  of  rivers, 


X 


INTEODUCTION. 


geology  has  as  yet  revealed  nothing  definite  concerning  the  fresh¬ 
water  life  of  the  Cretaceous  and  Jurassic  periods.  In  the  case  of 
the  fishes  of  the  suborder  Ostariophysi  this  is  especially  unfortunate; 
because  it  is  clear  that  in  early  Tertiary  times  they  were  already 
well  differentiated,  and  it  is  probable  that  their  peculiarly  modified 
auditory  apparatus  was  originally  an  adaptation  to  the  circum¬ 
stances  of  life  in  a  confined  area.  Even  the  highly  specialised 
Siluroids  were  completely  developed  in  the  early  part  of  the  Eocene 
period  {BucTclandium^  p.  B30) ;  and  one  Eocene  skull  is  identical 
with  that  of  the  existing  genus  Arius  (p.  333).  The  Characinidae 
have  a  cranium  not  much  more  advanced  than  that  of  Amia  ;  and 
as  these  seem  to  be  at  the  base  of  the  series  of  Ostariophysi,  the 
modification  of  the  auditory  apparatus  must  have  begun  in  a  very 
low  type  of  physostomous  fish. 


Apodes. 

The  eels  are  unique  among  the  so-called  teleostean  fishes  in 
possessing  more  than  five  basal  bones  in  the  pectoral  fin — a  feature 
characteristic  of  all  the  lower  groups  of  Actinopterygii.  Their 
skull  is  also  of  a  comparatively  primitive  type.  The  elongate  shape 
of  their  body,  the  loss  of  the  upper  part  of  their  pectoral  arch,  and 
the  complete  loss  of  their  pelvic  and  caudal  fins,  are  marks  of 
degenerate  specialisation.  Even  before  the  end  of  the  Cretaceous 
period  they  displayed  all  these  characteristics  except  the  lack  of 
the  caudal  fin  ;  for  Urenclielys  (p.  337),  from  the  Chalk  of  Mount 
Lebanon,  is  a  typical  generalised  eel  only  differing  from  the 
generalised  existing  genera  in  the  possession  of  a  small  separate 
caudal  fin.  It  therefore  seems  probable  that,  although  the  Apodes 
are  “  Teleostei”  in  the  sense  in  which  these  are  defined  by  Muller 
and  Griinther,  they  are  not  degenerate  members  of  any  group  of 
these  modern  fishes,  but  are  directly  derived  from  some  of  the 
Mesozoic  fishes  which  would  be  termed  “  Ganoidei  ”  by  the  same 
authors.  At  least  they  cannot  be  regarded  as  degenerate  members 
of  any  group  of  Cretaceous  “  Teleostei  ”  hitherto  discovered. 

Peecesoces. 

Spinous  fin-rays,  except  as  mere  basal  fulcra,  are  unknown 
before  the  Cretaceous  period ;  and  the  earliest  type  of  fish  in  which 
they  form  a  conspicuous  feature  of  the  dorsal  fin  is  Crossognathus 
(p.  348),  from  the  Neocomian  of  Switzerland  and  Germany.  In  its 


IXTKODUCTIOX. 


XI 


osteology,  so  far  as  known,  this  fish  seems  to  agree  very  closely 
with  the  existing  Atherines  ;  but  it  clifi“ers  in  having  one  continuous 
dorsal  fin,  with  the  right  and  left  halves  of  each  spine  not  com¬ 
pletely  fused  together.  Another  genus,  Syllceraus.  from  the  English 
and  IN’orth  American  Chalk,  is  nearly  similar.  The  Crossognathidae 
are  therefore  probably  the  Cretaceous  forerunners  of  the  Percesoces, 
which  were  already  completely  differentiated  into  their  surviving 
families  before  the  close  of  the  Eocene  period.  Atherina^  Mugil, 
and  Spliyrcena  all  date  from  the  Epper  Eocene  or  Oligocene.  The 
only  noteworthy  extinct  genus,  the  European  Oligocene  Cohiiopsis, 
belongs  to  the  Ammodytidae  and  retains  the  pelvic  fins  which  have 
disappeared  in  the  existing  genera. 

Hemibeaxchii, 

Among  extinct  Tertiary  fishes  there  are  several  so  closely  similar 
to  existing  Hemibranchs  and  Lophobranchs,  that  there  need  be  no 
hesitation  in  associating  them  with  the  latter.  As  yet,  however, 
they  afford  no  clue  to  the  origin  of  this  group.  The  comparatively 
generalised  Gasterosteidae  are  not  represented;  hut  all  the  other 
known  families  seem  to  date  back  to  the  Eocene  period.  Even  the 
Centriscidae  and  Syngnathidae  have  scarcely  changed  since  that 
time.  The  highl3’-specialised  Ampliisile  seems  to  have  persisted 
without  any  essential  modification  in  its  armour ;  while  Hippo¬ 
campus  appears  to  have  only  lost  its  caudal  fin  in  the  interval. 

Acaxthopteetgii. 

The  study  of  the  existing  fauna  has  already  suggested  that  the 
oldest  true  acanthopterygian  fishes  are  comprised  among  the 
Berycoids  and  Scombroids.  It  is  therefore  interesting  to  find  that 
most,  if  not  all,  of  the  typical  Cretaceous  Acanthopterj’gii  are 
referable  to  these  two  groups.  The  Epper  Cretaceous  genera  are, 
indeed,  very  little  specialised ;  and  it  seems  probable  that  they 
actually  originated  at  about  the  period  of  deposition  of  the  Chalk  in 
the  northern  hemisphere.  All  are  characterised  by  a  single  dorsal 
fin,  no  distinct  cleft  having  yet  appeared  between  the  spinous  and 
persistently  soft  portions.  Some  undoubtedly  Berycoid  genera 
(e.  g.  Hoplopteryx,  p.  396)  exhibit  an  excessive  development  of 
mucus-cavities  on  the  head. 

One  genus  (Prolates),  from  the  uppermost  Cretaceous  horizon  in 
France,  is  probably  a  true  Percoid.  It  marks  the  dawn  of  the

higher  groups,  and  must  have  been  contemporaneous  with  many 
unknown  Acanthopterygii  which  rapidly  became  differentiated  into 
various  families  in  seas  of  which  the  sediments  still  remain 
undiscovered  or  unexplored.  Palaeontology  has,  indeed,  hitherto 
revealed  as  little  concerning  the  origin  of  the  dominant  Tertiary 
fishes  as  of  the  Tertiary  mammals.  According  to  present  knowledge, 
all  the  principal  types  had  already  appeared  early  in  the  Eocene 
period ;  and  among  these  fishes  there  are  many  which  cannot  be 
distinguished  by  their  skeleton  from  genera  which  still  survive. 

The  Eocene  Acanthopterygii  are  best  known  by  imperfect  skulls 
and  other  uncrushed  fossils  from  the  Lower  Eocene  London  Clay  of 
Sheppey,  and  by  compressed  skeletons  from  the  fissile  Upper  Eocene 
limestone  of  ISTorthern  Italy.  Freshwater  fishes,  perhaps  of  the 
same  age,  are  also  represented  by  good  skeletons  in  the  Green  Liver 
Shales  of  Wyoming,  U.S.A.  Among  the  Berycoids  there  are  none 
particularly  remarkable ;  but  the  Scombroid  family  of  Carangidae 
includes  some  of  its  most  specialised  and  aberrant  genera,  such  as 
Vomeropsis  and  Mene^  of  which  the  latter  has  survived  unchanged 
until  the  present  day.  Among  extinct  fishes  to  be  placed  near  the 
Scombroids,  the  most  remarkable  are  the  highly  specialised  Palseo- 
rhynchidse,  which  range  from  the  Lower  Eocene  to  the  Lower 
Miocene.  Among  Percoids  the  fragmentary  fossils  suggest  that  the 
families  were  less  differentiated  in  the  Eocene  period  than  they  are 
at  the  present  day  ;  but  one  curious  specialisation,  the  fusion  of  the 
lower  pharyngeal  bones  now  so  characteristic  of  the  Labridse  and 
Chromidse,  had  already  been  acquired  by  several  genera.  The 
Plectognathi  were  also  less  completely  differentiated  from  the 
Chaetodonts  than  they  are  in  the  existing  fauna.  The  Scorpaenoids 
are  represented  in  the  Lower  Eocene  by  one  imperfectly  known 
genus  (^Amplieristus),  which  has  a  typically  armoured  skull  and 
cheek.  The  Cottoids,  Gobioids,  and  Blennioids  also  appear  to  be 
recognisable ;  and  with  the  latter  may  possibly  be  associated  the 
problematical  genus  Blocliius^  which  does  not  range  beyond  Eocene 
formations. 

Even  after  the  Eocene  period  the  history  of  the  Acanthopterygii 
cannot  be  clearly  traced.  Most  of  the  known  fossils  are  too 
imperfect  for  satisfactory  determination  ;  for  the  constant  distinctive 
characters  of  these  highly  specialised  fishes  are  of  a  minor  kind  and 
often  quite  inconspicuous  compared  with  those  which  permit  the 
classification  of  the  lower  grades.  Moreover,  a  very  large  pro¬ 
portion  of  the  species  are  represented  solely  by  the  detached  otoliths,

■which  cannot  always  be  identified  with  much  certainty  or  precision. 
The  Catalogue  of  the  extinct  Acanthopterygii  is  thus,  for  the  most 
part,  a  bare  list  of  names  of  fragmentary  fossils,  to  which  an 
approximate  and  provisional  systematic  position  has  been  assigned. 
This  circumstance  is  all  the  more  regrettable,  since  no  satisfactory 
classification  of  the  surviving  Acanthopterygii  has  hitherto  been 
proposed,  and  the  aid  of  Palaeontology  is  much  needed  for  its 
accomplishment. 


Axacanthixi. 

Typical  cod-fishes  and  flat-fishes  date  back  to  the  Oligocene  and 
Upper  Eocene  periods  respectively.  No  generalised  ancestors  of 
either  type  have  hitherto  been  recognised. 


'With  fragmentary  materials  of  this  nature,  it  is  impossible  to 
attempt  a  very  exact  classification.  It  has,  therefore,  been  deemed 
advisable  to  adopt  a  broad  conception  of  families  and  genera  more  in 
accordance  with  that  of  Ur.  Gunther  than  with  that  of  later  writers. 
This  corresponds  with  the  method  of  treatment  followed  in  the 
earlier  parts  of  the  Catalogue,  and  still  seems  adequate  for  a 
s}Tioptical  work  of  which  the  results  can  only  be  provisional.  Lists 
of  the  specimens  in  the  Museum  and  the  published  names  of  fossils 
not  represented  in  this  collection  have  been  arranged  approximately 
in  their  natural  order  for  convenience  of  reference,  without  any 
detailed  discussion  of  their  affinities.  The  incorporated  new  matter, 
indeed,  relates  rather  to  the  facts  of  osteology  than  to  premature 
essays  in  taxonomy.  A  detailed  knowledge  of  the  skeleton  of  the 
early  bony  fishes  of  the  Cretaceous  period  is  particularly  important ; 
and  the  writer  has  made  special  efforts  to  discover  the  essential 
facts  by  studying  most  of  the  available  collections.  He  is  indebted 
to  the  Lev.  William  Eird  and  Professor  Alfred  Ely  Day  for  the 
opportunity  of  examining  the  fine  series  of  Cretaceous  fishes  from 
Mount  Lebanon  in  the  Syrian  Protestant  College  at  Peyrout ;  to 
Professor  Karl  Busz  for  permission  to  study  the  unique  collection  of 
Westphalian  Cretaceous  fishes  in  the  Academy  of  Munster;  and  to 
Professor  S.  W.  Williston,  for  the  privilege  of  making  a  detailed 
examination  of  the  remarkable  remains  of  fishes  from  the  Kansas 
Chalk,  now  in  the  Museum  of  the  State  University  of  Kansas.  A 
brief  survey  of  the  Cretaceous  fishes  from  Northern  Brazil  in  the

INTRODUCTION. 


National  Museum  at  Eio  de  Janeiro,  made  "with  the  kind  help 
of  Professor  Orville  A.  Derby,  has  also  yielded  some  new  facts ; 
while  a  study  of  the  small  series  of  Swiss  Neocomian  fishes  and 
Lebanon  Cretaceous  fishes  at  Geneva,  thanks  to  the  kindness  of 
Drs.  Bedot  and  Weber,  has  elucidated  several  points  left  doubtful 
by  PictePs  original  descriptions.  The  Museums  of  the  Universities 
of  Munich  and  Naples  have  been  re-visited  ;  while  the  Woodwardian 
Museum  at  Cambridge,  and  the  Willett  Collection  in  the  Brighton 
Museum,  have  proved  as  useful  to  the  author  now  as  in  the  prepara¬ 
tion  of  the  previous  volumes  of  the  Catalogue.  Thanks  are  not  only 
due  to  the  many  friends  and  colleagues  in  Palaeontology  who  have 
facilitated  these  researches,  but  also  to  Mr.  G.  A.  Boulenger,  P.B.S., 
whose  valuable  advice  and  assistance  have  been  continually  at 
the  writer’s  disposal,  and  whose  opinions  concerning  the  general 
relationships  of  the  higher  fishes  ^  correspond  very  closely  with  those 
suggested  by  this  Catalogue.

Head  large  ;  maxilla  arched,  with  a  slightly  convex  dentigerous 
border  ;  mandible  prominent,  the  dentary  gradually  deepening  from 
the  symphysis  backwards  without  any  marked  thickening ;  teeth 
minute  and  closely  arranged.  Opercular  and  branchiostegal  appa¬ 
ratus  apparently  as  in  Leptolepis.  Vertebral  centra  in  form  of 
delicate  constricted  cylinders.  Pectoral  fins  much  larger  than  the 
pelvic  pair ;  dorsal  fin  small  and  short-based,  opposite  to  the  anal 
fin,  which  is  not  longer  than  deep  ;  caudal  fin  forked.  Scales  com¬ 
pletely  covering  the  trunk,  none  enlarged  or  thickened. 


Recent  researches  seem  to  necessitate  a  modification  of  the  definition  of  the 
Isospondyli  given  in  Part  III.,  p.  446,  by  the  omission  of  the  statements 
“  symplectic  bone  present”  and  “  precoi*acoid  arch  present.”  The  suborder  is 
thus  made  to  include  the  so  called  Scyphophori  and  Haplomi  of  Cope.  Oon- 
vuA  cerning  the  former  (Mormyridse  and  Gyinnarchida)  see  Gr.  A.  Boulenger,  Proc. 
Zool.  Soc.  1898,  pp.  775-821.

2  ACTINOPTERYGII. 

The  feeble  development  of  the  vertebral  centra  suggests  the  early 
Jurassic  age  of  this  fish.  As  observed  by  J.  Miiller,  the  genus  is 
closely  related  to  Thrmops  ;  but  it  is  distinguished  by  the  characters 
of  the  vertebrae  and  the  considerably  less  extension  of  the  anal  fin.

Type.  Nearly  complete  fish ;  Imperial  Academy  of  Sciences, 
St.  Petersburg. 

The  type  species,  attaining  a  length  of  about  0*1.  Length  of  head 
with  opercular  apparatus  slightly  exceeding  the  maximum  depth  of 
the  trunk  and  occupying  about  one  quarter  of  the  total  length  to 
the  base  of  the  caudal  fin.  Pectoral  fins,  when  adpressed,  reaching 
considerably  more  than  half  way  to  the  origin  of  the  pelvic  pair, 
which  arise  about  midway  between  the  pectorals  and  the  anal ; 
dorsal  fin  with  10  rays,  arising  immediately  behind  the  origin  of 
the  anal  fin,  which  comprises  14  rays,  the  length  of  the  longest 
about  equal  to  the  depth  of  the  caudal  region  at  its  insertion. 

This  fish  was  erroneously  supposed  by  Egerton  to  belong  to  the 
Cyprinoid  genus  Aspius  (T.  R.  Jones,  Mon.  Eoss.  Estherise,  Pal.  Soc. 

1862,  p.  112). 

Form.  ^  Loc.  Lower  Jurassic  (?) :  Turga,  Nertchinsk,  Transbaikal 
Province,  Siberia. 

P.,  273.  Six  small  pieces  of  shale  exhibiting  various  remains  of  this 
fish  associated  with  Estheria  middendorffii  (T.  R.  Jones, 

'  Mon.  Eoss.  Estherise,  Pal.  Soc.  1862,  p.  112),  collected  at 

Turga  by  C.  G.  Austin.  One  specimen  (numbered  P.  273  ct) 
also  displays  remains  of  comparatively  large  fins  which 
may  belong  to  the  genus  Belonorhynchus. 

Transferred  from  Mus.  Practiced  Geology,  1880.

P.  6728.  Slab  exhibiting  two  imperfect  small  fishes.

LEPTOLEPIDJE.  3 

liycoptera.  sinensis,  sp.  nov. 

[Eestoration  in  text-figure  1.] 

Ty^e.  Imperfect  fish  ;  British  Museum. 

A  species  attaining  a  length  of  about  0*13.  Length  of  head  with 
opercular  apparatus  slightly  less  than  the  maximum  depth  of  the 
trunk  and  occupying  scarcely  more  than  one  quarter  of  the  total 
length  to  the  base  of  the  caudal  fin.  Vertebrae  about  45  in  number, 
20  being  caudal.  Pectoral  fins,  when  adpressed,  scarcely  reaching 
more  than  half  way  to  the  origin  of  the  pelvic  pair ;  other  fins 
apparently  as  in  the  type  species. 

Form.  Log.  Lower  Jurassic  (?) :  Poh-tse,  near  Layang  Nsien, 
Province  of  Shantung,  China. 

P.  7358.  Type  specimen,  collected  by  H.  M.  Becher.  Among  the 
remains  of  the  head,  the  small  mouth  is  distinct,  bounded 
above  both  by  the  premaxilla  and  the  long  arched  maxilla 
Traces  of  small,  bluntly  conical  teeth  are  also  distinguish¬ 
able.  Indications  of  a  few  slender  branchiostegal  rays 


Pig.  1. 


occur  below  the  hinder  end  of  the  mandible.  The  delicate 
vertebral  centra  are  very  imperfectly  preserved,  but  18  or 
19  pairs  of  stout  ribs  can  be  counted,  and  these  almost  or 
completely  encircle  the  abdominal  cavity.  The  neura 
and  hsemal  spines  in  the  caudal  region  are  comparatively 
small,  except  at  the  base  of  the  caudal  fin.  The  fish  is 
distorted  in  the  anterior  part  of  the  caudal  region,  but  all 
the  fins  are  tolerably  well  preserved.  Purchased,  1894. 

P.  7357.  Contorted  specimen  in  counterpart,  collected  by  H.  M. 

Becher.  One  of  the  slabs  exhibits  a  second  well-preserved 
fish  on  the  obverse  side.  The  characteristic  jaws,  dentition,

and  opercular  apparatus  are  distinct;  and  the  delicate 
cylinders  forming  the  vertebral  centra  are  well  shown. 

Purchased^  1894. 

P.  7090.  Imperfect  impression  of  large  fish,  and  greater  portion  of 
trunk  of  a  smaller  specimen.  The  latter  displays  the 
delicate  vertebral  centra  and  the  thin  scales  marked  with 
fine  longitudinal  striations. 

Presented  hy  Barry  M.  Beelier^  Esq.,  1894. 

P.  7095.  Disptorted  specimen,  artificially  polished.  Purchased, 

To  Lycoqqtera  may  also  probably  be  referred  the  so-called  Prolebias 
davidi  (H.  E.  Sauvage,  Bull.  8oc.  Geol.  France,  [3]  vol.  viii.  1880, 
p.  452,  pi.  xiii.  figs.  5,  6).  It  is  described  as  abundant  in  a  whitish 
shaly  limestone  “  belonging  to  the  Tertiary  formations  of  N’orthern 
China.’*  It  is  not  represented  in  the  Collection.

Genus  OSMEROIDES9  Agassiz 
[Poiss.  Foss.  vol.  V.  pt.  ii.  1844,  p.  103.] 

Svn.  Rhabdolepis,  W.  von  der  Marck  (non  Troscliel,  1857),  Palaeontogr. 
vol.  xi.  1863,  p.  26. 

Holcolepis,  W.  von  der  Marck,  ihid.  vol.  xv.  1868,  p.  278. 

Head  and  trunk  not  much  laterally  compressed,  and  abdomen 
flattened.  Parietal  bones  in  contact  in  the  median  line ;  mandible 
a  little  prominent,  and  gape  not  extending  behind  the  eye ;  two 
supramaxillary  bones;  margin  of  the  jaws  and  some  inner  bones 
with  clusters  of  minute  bluntly-pointed  teeth,  sometimes  perhaps 
tritoral.  Branchiostegal  rays  about  20  in  number,  about  five  of 
the  uppermost  and  broadest  supported  by  the  epihyal.  Yertebrm 
between  50  and  70  in  number,  about  20  being  caudal;  the  centra 
not  longer  than  deep,  aU  slightly  constricted  and  marked  with 
small  irregular  longitudinal  ridges.  No  enlarged  scale  at  the  base 
of  the  paired  fins ;  dorsal  fin  never  much  longer  than  deep,  opposite 
or  nearly  opposite  the  pelvic  pair ;  anal  smaller  than  the  dorsal  fin ; 
caudal  fin  forked ;  no  fin-rays  excessively  elongated.  Scales  often 
ornamented  in  their  exposed  portion  with  delicate  radiating  lines 
of  minute  tubercles,  marked  in  their  covered  portion  with  a  few 
radiating  grooves  terminating  in  notches  at  the  anterior  truncated 
margin  ;  hinder  margin  not  serrated ;  course  of  lateral  line  indicated 
by  a  feeble  ridge  and  a  notch  in  the  hinder  border  of  most  of  the 
scales. 

The  generic  name  Osmer aides  was  originally  given  by  Agassiz  to 
some  fishes  from  the  Cretaceous  of  Westphalia  catalogued  below 
in  the  family  Scopelidse  {Sardinioides  monasteri).  When  it  was 
afterwards  applied  to  fossils  discovered  by  Dr.  Mantell  in  the 
English  Chalk,  Agassiz  expressly  stated  that  the  determination  of 
generic  identity  w^as  uncertain  and  provisional.  In  course  of  time, 
however,  the  name  has  become  universally  recognised  as  belonging 
to  the  English  specimens,  and  least  confusion  will  be  caused  in 
established  nomenclature  if  Osmeroides  leiuesiensis  be  regarded  as 
the  type  species.

Type.  Imperfect  fish  ;  British  Museum. 

The  type  species,  attaining  a  length  of  about  0*45.  Form  and 
proportions  not  definitely  known,  but  length  of  head  with  opercular 
apparatus  contained  nearly  three  times  in  the  length  of  the  trunk 
from  the  pectoral  arch  to  the  base  of  the  caudal  fin.  Length  of 
cranium  somewhat  exceeding  twice  its  maximum  width  at  the 
occiput ;  bones  of  the  hinder  half  of  the  cranial  roof,  cheek-plates, 
opercular  bones,  and  upper  branchiostegal  rays  ornamented  with 
coarse  radiating  rugae.  Bays  of  each  pelvic  fin  not  less  than  1 1  in 
number;  the  small  anal  nearer  to  the  caudal  than  to  the  pelvic 
pair.  Exposed  area  of  scales  narrow  and  deep,  usually  smooth, 
sometimes  ornamented  with  verj^  fine  closely-arranged  radiating 
lines  of  tubercles. 

The  principal  features  of  the  collection  from  the  English  Chalk 
enumerated  below  are  described  in  the  Proc.  Zool.  Soc.  1894  (1895), 
pp.  656-659,  pi.  xlii.,  and  include  all  the  more  important  osteo- 
logical  characters  of  the  genus.  The  lack  of  more  precise  information 
concerning  the  proportions  of  the  fish  and  its  fins,  however,  renders 
it  impossible  to  determine  at  present  whether  the  fragmentaiy 
specimens  of  Osmeroides  from  the  Turonian  and  Senonian  of 
Bohemia,  described  by  Fritsch  and  Laube  (loe.  cit.),  truly  belong 
to  the  same  species.  In  any  case,  Fritsch’s  outline-restoration  of 
“  Osmeroides  leiuesiends,  Ag.,”  is  much  too  slender  and  has  too  small 
a  head  for  this  fish,  while  the  anal  fin  is  not  sufiiciently  remote. 
As  shown  by  the  English  fossils,  the  cranial  osteology  differs  much 
from  the  tentative  restorations  both  of  Fritsch  and  Laube.

Type.  Imperfect  fish  ;  Edinburgh  Museum  of  Science  and  Art. 

Length  of  head  with  opercular  apparatus  nearly  equalling  half 
that  of  the  trunk  from  the  pectoral  arch  to  the  base  of  the  caudal 
fin.  Cranial  roof,  opercular  bones,  and  upper  branchiostegal  rays 
smooth  and  unornamented ;  a  few  minute  tritoral  teeth  within  the 
mouth.  About  40  abdominal  and  20  caudal  vertebrae.  Dorsal  fin 
comprising  20  rays,  the  distance  between  its  origin  and  the  occiput 
somewhat  less  than  that  between  its  termination  and  the  base  of  the 
caudal  tin  ;  pelvic  fins  opposite  the  hinder  half  of  the  dorsal ;  anal 
fin  small,  with  not  more /than  8  or  10  rays,  arising  nearer  to  the 
caudal  than  to  the  pelvic  pair.  Radiating  grooves  in  overlapped 
portion  of  scales  especially  conspicuous. 

The  type  specimen  of  this  species  is  evidently  lengthened  by 
crushing,  and  the  rotund  form  of  the  fish  causes  the  mode  of 
distortion  of  the  different  specimens  to  be  very  varied.  It  is  thus 
difficult  to  determine  the  original  proportions  of  the  species. 

Form.  Loc.  Upper  Cretaceous :  Sahel  Alma,  Mount  Lebanon.

and  figured  by  Davis,  Minute  blunt  teeth  are  observed 
in  the  mandible,  and  the  foremost  branchiostegal  rays  are 
very  numerous  and  slender.  The  vertebrae  cannot  be 
counted  in  the  abdominal  region,  but  the  caudals  are  about 
20  in  number  in  advance  of  the  hypural.  Small  inter¬ 
muscular  bones  are  conspicuous  in  both  regions.  The 
dorsal  fin  is  distinctly  longer  than  deep,  though  imperfect ; 
the  anal  fin  exhibits  10  supports.  Lewis  Coll.

fig.  3,  from  the  left  lateral  aspect.  Traces  of  the  minute 
blunt  teeth  are  seen  in  the  jaws,  and  the  upper  branchi¬ 
ostegal  rays  are  shown  to  be  comparatively  short  and 
broad.  The  characteristic  vertebral  centra  are  dis^Dlayed, 
nearly  all  slightly  deeper  than  long,  20  or  21  belonging 
to  the  caudal  region  in  advance  of  the  hypural,  and  35 
shown  in  the  abdominal  region  behind  the  posterior 
margin  of  the  operculum.  The  ribs  and  intermuscular 
bones  are  very  slender ;  the  expanded  haemal  and  neural 
spines  at  tlie  base  of  the  caudal  fin  resemble  those  in  the 
typical  0.  lewesiensis.  The  dorsal  fin  is  apparently  nearly 
complete,  exhibiting  17  or  18  supports  and  as  many  rays, 
the  latter  readily  splitting  into  their  two  halves  and  very 
closely  articulated  distally ;  its  extent  equals  the  distance 
between  it  and  the  caudal  fin.  The  small  anal  fin  has 
at  least  9  rays,  which,  like  those  of  the  dorsal,  caudal, 
and  pelvic  fins,  are  very  closely  articulated  distally.  The 
exposed  area  of  the  scales  is  much  deeper  than  bioad, 
and  apparently  smooth.

this  genus  has  not  hitherto  been  recognised  among  extinct  fishes. 
To  it,  however,  may  probably  be  referred  the  following  two  speci¬ 
mens,  which  are  too  imperfect  for  precise  determination  : — 

39443.  Imperfect  head  and  abdominal  region  of  trunks  much  crushed 
and  obscured  by  decaying  pyrites  ;  London  Clay,  Sheppey. 
The  length  of  the  head  with  opercular  apparatus  is  about 
O’ 14,  and  the  distance  from  the  base  of  the  pectoral  to 
what  seems  to  be  the  origin  of  the  pelvic  fins  is  not  less 
than  0*18.  The  middle  of  the  cranial  roof  exhibits  a 
depression,  gradually  widening  from  the  occiput  to  the 
hinder  border  of  the  orbits,  then  somewhat  contracted 
again  forwards.  The  large  posterior  suborbitals  and 
ossified  sclerotic  are  conspicuous  ;  the  very  wide  gape, 
prominent  mandible,  and  gently  arched  maxilla  are  also 
shown,  without  any  traces  of  teeth.  The  mandibular 
rami  are  crushed  together  and  imperfect,  thus  destroying 
the  branchiostegal  apparatus  between  them.  Part  of  the 
left  pectoral  fin  is  preserved,  and  at  the  hinder  end  of  the 
fossil  there  is  apparently  the  base  of  the  right  pelvic  fin. 
A  well-ossified  vertebral  centrum,  not  pitted  but  feebly 
striated  on  the  side,  also  projects  through  the  squamation 
at  the  hinder  end  of  the  abdominal  region.  The  scales 
are  beautifully  ornamented  in  their  exposed  portion  with 
fine  radiating  ridges.  Bowerhank  Coll. 

P.  1762.  Portion  of  trank  of  the  same  species,  also  much  pyritised  ; 

London  Clay,  Sheppey.  Robust  vertebral  centra  are  ex¬ 
hibited,  each  about  as  long  as  deep,  not  pitted  at  the  sides 
but  feebly  striated ;  the  neural  arches  are  broken  away, 
but  seem  to  have  been  fused  with  the  centra.  Portions  of 
the  pelvic  fins  are  preserved,  and  the  scales  are  ornamented 
as  in  the  last  specimen.  Egerton  Coll. 

The  following  specimen  was  supposed  by  Agassiz  to  represent  a 
genus  allied  to  Elojgs  : —

margin  of  the  jaws,  the  vomer,  parasphenoid,  palatine,  and  ptery¬ 
goid  bones,  and  the  tongue,  with  clusters  of  minute  pointed  teeth. 
Gill-rakers  long  and  slender ;  operculum  subdivided  by  transverse 
suture;  branchiostegal  rays  about  25  in  number.  Pectoral  and 
pelvic  flns  each  with  an  enlarged  and  elongated  scale  at  the  base ; 
dorsal  fln  short-based  and  elevated,  with  much-produced  hindermost

Type.  Imperfect  head ;  British  Museum. 

An  imperfectly  known  large  species,  the  head  with  opercular 
apparatus  attaining  a  length  of  at  least  0-3.  Length  of  head  nearly 
equalling  its  depth  behind,  and  about  twice  as  great  as  the  maximum 
width  of  the  operculum  ;  length  of  cranial  roof  from  occiput  to  post¬ 
frontal  considerably  less  than  its  width  at  the  position  of  the  latter 
element.  Maxilla  extending  backwards  beyond  the  orbit ;  opercular 
bones  and  cneeK-piates  radiately  sculptured.

from  the  occiput  to  the  prefrontal  region  immediately  in 
advance  of  the  eye.  A  certain  amount  of  crushing  and 
distortion  is  at  the  same  time  obvious.  The  sclerotic  (set,) 
is  ossified  and,  unless  appearances  are  deceptive,  the  eye 
is  smaller  than  in  the  recent  ih.  cyprinoides.  Remains  of 
the  delicate  cheek-plates,  with  radiating  markings,  are  pre¬ 
served  both  behind  (s.o.)  and  in  front  (a.o.)  of  the  eye.  The 
relatively  small  premaxilla  (pma?.)  underlaps  the  front  ex¬ 
tremity  of  the  enormous  maxilla  {mx.),  which  exhibits  a 
small  knob  (a\)  for  its  anterior  attachment  to  an  inner 
element.  The  extent  of  the  supramaxillaries  is  indicated 
only  by  the  depression  for  their  overlap  of  the  maxilla. 
The  whole  length  of  the  left  mandibular  ramus  is  displayed 
(cZ.),  with  its  hollowed  hinder  articulation  in  contact 
with  the  condyle  of  the  quadrate  {qud) ;  and  the  latter 
element  is  directly  apposed  to  the  metapterygoid  above, 
while  apparently  provided  with  a  superiorly-pointed, 
slender,  hinder  process  to  grasp  the  small  symplectic. 
The  bases  of  clustered  series  of  verj"  minute  teeth  are 
shown  on  the  margin  of  the  jaws  where  preserved.  The 
upper  end  of  the  hyomandibular  (Jim.)  is  partly  exposed, 
with  its  process  for  the  support  of  the  operculum  [op.) ; 
and  the  latter  element  is  well  shown,  with  the  pre¬ 
operculum  {p.op.)  in  front,  and  the  suboperculum  {s.op.) 
and  interoperculum  (i.op.)  below.  The  spaced  series  of 
branchiostegal  rays  (hr.)  cannot  have  numbered  less  than 
20,  although  not  so  many  are  actually  exhibited ;  and  the 
gular  plate  (yi^^.)  is  nearly  half  as  loug  as  the  mandible.

P.  637.  Hinder  half  of  skull,  labelled  Hypsodon  toliapicus  by  Agassiz, 
and  intended  to  be  the  type  specimen  of  that  species.  The 
cranial  roof  is  shown  from  above  of  two  thirds  the  natural 
size  in  PI.  III.  fig.  4,  and  the  various  elements  can  be 
readily  distinguished  as  lettered.  On  the  occipital  face 
the  exoccipital  is  shown  to  meet  its  fellow  in  the  median 
line  below  the  large,  keeled  supraoccipital ;  but  the  basi- 
occipital  is  broken  and  crushed  to  the  left,  with  one  short 
and  deep  vertebral  centrum  adhering  to  it.  There  is  clear 
evidence  of  a  basicranial  canal.  The  otic  region  exhibits 
its  characteristic  conformation,  and  an  elongated  facette 
for  the  hyomandibular  is  shown  on  the  pterotic.

P.  356.  Imperfect  hinder  portion  of  skull,  longitudinally  bisected  in 
the  median  line  to  exhibit  the  extent  of  the  supraoccipital 
bone.  As  shown  in  the  section  (PI.  III.  fig.  5),  this 
element  (s.occ.)  is  much  thickened,  and  in  its  upper 
portion  extends  almost  as  far  forwards  as  the  investing 
parietals  {pa.').  The  exoccipitals  {ex.occ.),  as  in  the  pre¬ 
ceding  specimen,  clearly  form  the  upper  border  of  the 
foramen  magnum  ;  and  there  seems  to  be  a  persistent 
suture  between  the  basioccipital  (b.occ.)  and  basisphenoid 
(h.sp.).  When  viewed  from  behind  (fig.  5  a),  the  basi¬ 
occipital  exhibits  the  groove  for  the  basicranial  canal 
(b  e.).  Egerton  Coll. 

P.  4153.  Imperfect  hinder  portion  of  skull,  smaller  than  the  pre¬ 
ceding.  The  basicranial  canal  is  indicated,  and  the 
remains  of  the  otic  region  (PI.  III.  fig.  6)  are  interesting. 
The  pro-otic  {pr.o.),  pierced  as  usual  by  the  oval  foramen 
for  the  fifth  nerve,  is  in  contact  above  with  the  sphe- 
notic  or  postfrontal  (pt.f.)  and  the  pterotic  (pt.o.),  these 
two  latter  bones  meeting  and  forming  the  floor  of  a  cavity 
which  exists  between  the  outer  part  of  the  otic  mass  and 
the  squamosal  {sq.).  The  upper  end  of  the  hyomandibular 
must  have  articulated  with  two  distinct  facettes  (/.),  the 
largest  and  deepest  on  the  pterotic,  the  smallest  at  the 
point  of  contact  of  the  sphenotic  with  its  adjacent  elements 
already  mentioned.  There  are  indications  of  the  great 
triangular  hollow  in  the  otic  mass  immediately  behind  the 
pro-otic,  and  of  the  similar  hollow  on  the  occipital  face 
between  the  outer  edges  of  the  epiotic  and  pterotic.

P.  634.  The  type  specimen  labelled  by  Agassiz.  It  is  the  much- 
abraded  cranium,  wanting  the  region  in  advance  of  the 
postfrontals.  The  parietal  bones  are  almost  completely 
removed,  thus  exposing  the  supraoccipital  which  extends 
forwards  beneath  them.  The  characteristic  otic  region  is 
well  shown  on  tbe  right  side,  and  the  basicranial  canal  is 
indicated  beneath  the  axis  of  the  cranium.  Egerton  Coll. 

The  following  skull  also  appears  to  belong  to  a  species  of  Megaloios., 
characterised  by  a  relatively  short  otic  region,  the  length  of  the 
cranial  roof  from  the  occiput  to  the  postfrontal  not  exceeding  half  its 
width  at  the  position  of  the  latter  element : — 

P.  9192.  Cranium  0T25  in  length ;  London  Clay,  Sheppey.  The  roof 
exhibits  the  characteristic  arrangement  of  the  bones,  and 
the  basicranial  axis  is  bent  upwards  as  usual  at  the  ante¬ 
rior  end  of  the  otic  region.  The  presence  of  a  basicranial 
canal  is  clearly  indicated,  but  there  does  not  appear  to  be 
a  vertebral  centrum  fused  with  the  basioccipital.  The 
parasphenoid  is  abraded,  but  the  spatulate  vomer  is  shown 
to  have  been  covered  with  minute  teeth.  The  long  laminar 
entopterygoid  is  preserved  on  the  left  side,  but  its  exposed 
oral  face  is  abraded.  History  unhiown.

37981.  Type  specimen,  a  vertically  crushed  imperfect  head,  shown 
of  two-thirds  the  natural  size  in  PI.  Y.  hg.  1  ;  Lower 
Chalk,  Hollingbourn,  Kent.  The  cranial  roof  is  well 
exposed  but  damaged  by  an  oblique  fracture.  Its  most 
characteristic  feature  is  the  median  depression  in  the 
hinder  frontal  region,  where  the  bone  becomes  com¬ 
paratively  smooth.  A  trace  of  the  small,  finely-punctate 
supraoccipital  (s.occ.)  is  observed  at  the  hinder  border  of 
the  depression,  while  quite  posteriorly  on  the  left  side  an 
otic  bone  (apparently  epiotic,  ejo.o.)  is  crushed  outwards. 
The  limits  of  the  parietal  {pa.).,  squamosal  {sp),  and 
frontal  {fr.)  elements  can  also  be  distinguished ;  the  last- 
named  being  relatively  large  bones,  exhibiting  a  series 
of  pits  along  either  side  of  the  depression  where  traversed 
by  the  slime-canal.  The  terminal  ethmoid  (etli.),  finely 
punctate  like  the  supraoccipital,  is  relatively  small  and 
pointed  in  front,  without  any  expansion.  The  cheek- 
plates  are  best  shown  on  the  left  side,  where  the  posterior 
suborbitals  (5.0.)  with  their  slightly  radiating  furrows  are 
conspicuous.  The  sutures  between  these  are  not  distinct, 
and  it  is  not  quite  clear  whether  there  is  a  border  of  cir- 
cumorbitals  (c.o.)  between  them  and  the  orbit.  The  anterior 
of  the  two  circumorbitals  above  the  orbit  is  relatively 
large  and  arched,  curving  downwards  in  front  to  meet  the 
single  long  and  narrow  plate  bordering  the  orbit  beneath. 
There  is  also  one  small  triangular  antorbital  plate  {a.o.). 
The  maxilla  (m^.)  is  broken  in  front  by  a  fracture  and 
displacement  which  also  crosses  the  mandible.  It  is  over¬ 
lapped  for  about  half  its  length  by  the  supramaxilla 
(s.m.v.),  which  is  a  little  expanded  behind.  The  teeth 
in  its  anterior  half  are  only  about  half  as  large  as  those 
in  its  posterior  half.  The  premaxilla  {pmoc.)  is  a  thin 
triangular  bone,  sharply  notched  in  its  hinder  border, 
and  bearing  a  close  series  of  teeth  as  small  as  those  of  the 
front  part  of  the  maxilla.  The  mandible  is  also  delicate

and  much  tapering  at  the  symphysis.  The  articulo-angular 
element  is  very  short,  with  a  large  concave  articular 
facette  for  the  quadrate,  best  seen  on  the  right  side.  The 
dentary  (d.)  bears  a  spaced  series  of  teeth  slightly  larger 
even  than  the  largest  on  the  maxilla.  Of  the  opercular 
apparatus  only  fragments  remain.  The  preoperculum 
seems  to  have  been  very  narrow,  and  this  is  probably  the 
displaced  arched  bone  on  the  right  side  of  the  fossil,  not 
shown  in  the  figure.  Purchased^  1864. 

4055.  Slab  of  chalk  exhibiting  the  imperfect  hinder  half  of  a  larger 
skull  associated  with  a  quadrate,  vertebrae,  and  other 
fragments,  provisionally  referred  by  Agassiz,  loc.  cit.,  to 
Hypsodon  leiuesiensis ;  Chalk,  Sussex.  The  skull  and 
quadrate  bone  are  figured  by  Agassiz,  loc.  cit.  The  cranial 
roof  exhibits  the  characteristic  median  depression.  The 
vertebrae  are  shorter  than  deep  and  strengthened  by  deli¬ 
cate  longitudinal  ridges.  A  fragment  of  jaw  on  the  same 
slab  bears  traces  of  large  hollow  teeth  like  those  of  Por- 
tlieus ;  but,  if  the  determination  here  proposed  be  correct, 
this  cannot  have  belonged  to  the  same  fish  as  the  skull.

roof  is  shown  from  above,  of  the  natural  size,  in  PL  Y.

in  side-view  and  from  below  in  figs.  2 a,  2h.  The 
sutures  between  the  various  elements  of  the  cranial  roof 
are  distinct  and  arranged  as  already  described  in  the  type

well  shown.  The  anterior  vertebral  centra  do  not  exhibit 
lateral  pits,  except  one  facette  near  the  ventral  border 
for  the  articulation  of  the  rib  (r.).  Their  ventral  face, 
however,  is  pitted  and  strengthened  with  longitudinal

49826.  Type  specimen,  shown  of  the  natural  size  from  the  left 
side  in  PI.  VII.  fig.  4 ;  Lower  Chalk,  Lewes.  The  head 
is  imperfect  and  a  fracture  crosses  the  rostral  region 
causing  some  displacement ;  but  the  general  proportions 
seem  to  be  determinable  with  sufficient  accuracy.  The 
posterior  suborbital  plates  {s.o.)  are  exhibited  only 
in  an  impression  of  their  inner  face,  and  it  is  uncertain 
how  they  were  subdivided ;  the  transverse  fractures  may 
or  may  not  represent  sutures.  There  is  one  long  infra¬ 
orbital  (i.o.)  beneath  the  eye,  and  in  the  orbit  itself 
there  is  a  trace  of  an  ossified  sclerotic  (scl.).  The  long, 
slender  maxilla  imperfect  at  each  end,  has  a  very 

slightly  sinuous  oral  border  bearing  small  spaced  teeth. 
The  premaxilla  (j)mx.),  with  a  regular  series  of  larger 
and  more  slender  teeth,  is  about  one  quarter  as  much 
extended  as  the  maxilla.  The  mandible  is  imperfectly 
displayed,  but  the  anterior  end  of  the  dentary  (d.)  bears 
slender  teeth  intermediate  in  size  between  those  of  the 
premaxilla  and  maxilla.  The  lower  end  of  the  pre¬ 
operculum  {p.op.)  seems  to  be  completely  preserved, 
but  is  not  much  expanded  and  does  not  exhibit  any 
radiating  ridges.  The  operculum  fop.)  is  very  imperfectly 
shown,  chiefly  as  an  impression,  but  must  have  been 
nearly  twice  as  deep  as  broad.  The  suboperculum  {s.op.) 
is  shown  to  have  been  smooth,  with  feeble  traces  of 
radiating  lines,  and  its  width  is  about  as  great  as  its  depth. 
The  slender  clavicle  (cl.)  is  partially  exposed,  while  the 
post-temporal  {p.t.)  and  postclavicular  plates  {p.cl.)  are 
conspicuous.  A  few  of  the  anterior  scales  are  also  pre¬ 
served,  the  relatively  small  exposed  area  marked  with 
delicate  radiating  depressions.  Capron  Coll.

Among  the  fragments  of  jaws  the  most  conspicuous  is  the 
imperfect  right  dentary,  exposed  from  within  and  partly 
shown  in  Smith’s  upper  figure,  loc.  cit.  The  teeth  on  this 
bone  are  large  and  smooth,  curved  inwards,  and  arranged 
ill  very  close  series,  the  base  of  each  much  thicker 
measured  from  its  outer  to  its  inner  face  than  from  side 
to  side  ;  the  alveolar  border  is  greatly  thickened  to  support

this  dentition.  The  left  premaxilla,  exposed  from  the 
oral  aspect,  is  imperfectl}'  shown  in  Smith’s  lower  fignre  ; 
all  its  teeth  are  imperfect,  and  the  foremost  of  the  two 
large  inner  teeth  is  represented  only  by  its  hollow  base  ; 
of  the  six  outer  teeth  indicated,  two  exhibit  the  greater 
part  of  the  crown  and  prove  that  they  are  implanted 
almost  vertically.  Another  imperfect  dentigerous  bone 
shown  from  the  outer  aspect  on  the  upper  part  of  the  slab 
seems  to  be  the  left  maxilla.  Its  oral  border,  so  far  as 
preserved,  is  straight  and  bears  teeth  resembling  those  of 
the  mandible,  though  much  smaller ;  its  outer  face  is 
flattened,  but  shows  smooth  and  rounded  irregularities  ; 
it  is  deepest  in  the  anterior  third  but  soon  tapers  to  its 
anterior  articulation.  The  latter  is  shown  to  be  much 
horizontally  extended  in  a  fragment  of  the  right  maxilla. 
Some  bony  laminae  covered  with  a  cluster  of  minute 
pointed  teeth,  may  represent  the  entopter3'goid.  Three 
of  the  large  teeth  have  been  sliced  to  displa}"  their  pulp- 
cavity.  Among  other  fragments  maj’  be  noticed  one  of 
the  hyomandibulars,  remarkably  expanded  and  laminar 
in  form,  with  the  usual  process  for  the  support  of  the 
operculum.  Touhnin  Smith  Coll.

Chalk,  Litchling,  Sussex.  ]\Iost  of  the  outer  face  of  the 
cranium  is  destroyed ;  but  it  is  evident  that  the  middle  of 
the  roof  is  onl}"  gently  depressed,  while  the  supraoccipital 
reaches  the  frontals  and  prevents  the  parietals  from 
meeting  in  the  middle  line.  Part  of  the  ossified  sclerotic 
is  shown  on  the  left  side.  The  hinder  end  of  the  right 
maxilla  is  complete,  and  proves  that,  although  the  bone 
is  much  thickened  in  its  front  portion,  it  becomes  com¬ 
pressed  to  a  thin  vertical  lamina  behind.  Some  fragments 
of  inner  bones  of  the  mouth  exhibit  clustered  minute 
teeth,  as  in  the  previous  specimen.  Two  anterior  vertebrae 
are  much  deeper  than  long  and  not  pitted  at  the  sides.

A  renewed  examination  of  the  type  specimen  of  Mosasaurus 
gracilis,  Owen,  from  the  Chalk  of  Sussex,  in  the  Brighton  Museum, 
has  convinced  the  present  writer  that  the  fossil  is  truly  part  of  the 
mandible  of  a  Mosasaurian.  It  was  therefore  wrongly  named 
Pacliyrliizodus  gracilis  in  A.  S.  Woodward,  Proc.  Geol.  Assoc,

P.  1749.  Type  specimen,  shown  of  two  thirds  the  natural  size  from 
the  left  lateral  and  inferior  aspects  in  PI.  III.  figs.  1,  1  a. 
The  general  proportions  of  the  cranium  are  indicated,  but 
the  bones  are  much  fractured  and  some  may  be  distin¬ 
guished  more  readily  in  the  next  specimen.  The  otic 
region  is  well  ossified,  and  the  sphenotic  (or  postfrontal, 
jpt.f.)  enters  the  anterior  end  of  the  facctte  for  the  hyo- 
mandibular.  The  latter  element  Qim.)  is  much  constricted 
and  bent  forwards  mesially,  while  the  slender  process  (p.) 
for  the  support  of  the  operculum  (op.)  arises  from  the 
lower  end  of  its  upper  half.  This  bone  seems  to  be  a 
little  displaced  backwards  by  crushing,  the  remains  of  the 
quadrate  (qu-)  and  probably  of  the  symj)lectic  (sy.)  being 
well  forwards.  The  fragments  of  the  metapterygoid 
(mpt.)  and  ectopterygoid  (ecpt.)  do  not  suffice  for  descrip¬ 
tion.  The  snout  is  incomplete,  but  the  greater  part  of 
'  the  mandible  is  shown  on  each  side.  The  articulo-angular 
element  (ag.)  is  relatively  large,  with  very  low  articular 
facette ;  the  depth  of  the  coronoid  region  seems  to  have 
equalled  one  quarter  the  total  length  of  the  ramus,  and 
the  dentary  (d.)  gradually  tapers  forwards.  The  teeth  in 
the  anterior  half  of  the  mandible,  so  far  as  preserved,  are 
much  larger  than  those  in  its  posterior  half,  which  are 
best  seen  on  the  right  side.  All  are  smooth,  acutely 
pointed,  and  inclined  a  little  backwards.  Part  of  a  com¬ 
paratively  deep  suboperculum  (s.op.)  is  preserved ;  the 
uppermost  branchiostegal  ray  (hr.)  is  shown  to  be  rather 
large,  but  the  others,  not  less  than  14  in  number,  are 
only  imperfectly  indicated ;  the  gular  plate  (gu.)  wants 
merely  its  anterior  end.  Egerton  Coll. 

P.  640.  Another  imperfect  head,  displaying  the  hinder  part  of  the 
cranial  roof  (PI.  III.  fig.  2),  remains  of  the  characteristic 
cheek- plates,  and  part  of  the  opercular  apparatus.  This 
specimen  is  labelled  EurygnaiJius  cavifrons  by  Agassiz,  and 
was  intended  by  him  to  be  the  type  of  the  species.  The 
robust  supraoccipital  (s.occ.),  with  a  posterior  keel,  is  well 
shown  at  the  back  of  the  cranial  roof,  articulating  with 
the  large  epiotic  (epo.)  on  either  side.  The  frontals  (fr.) 
are  shown  to  extend  close  to  this  occipital  border ;  they 
are  bounded  on  either  side  in  their  hinder  portion  by 
membrane-bones  which  seem  to  be  identifiable  as  squa¬ 
mosal  (sq.),  but  the  parietals  cannot  be  recognised  with

certainty.  The  postfrontal  or  sphenotic  projects  a 

little  on  each  side  and  can  be  seen  from  above.  Remains 
of  the  eheek-plates  (s.o.)  on  both  sides  are  very  delicate, 
and  exhibit  the  characteristic  radiating  markings.  The 
jaws  are  too  imperfect  for  description,  but  one  of  the  cha¬ 
racteristic  hinder  mandibular  teeth  is  seen.  The  opercu¬ 
lum,  though  fragmentary,  is  shown  to  have  been  deeper 
than  broad  ;  while  the  preopercnlum,  must  clearly  have 
been  very  little  expanded  at  its  angle.  Of  the  gnlar  plate 
only  the  hinder  end  is  preserved.  Egerton  Coll.

Trunk  elongated  and  laterally  compressed,  abdomen  trenchant. 
Cheek-plates  robust,  exhibiting  radiating  branches  from  the  slime- 
canal;  jaws  toothless,  except  the  anterior  end  of  the  mandible, 
which  bears  one  or  two  pairs  of  large  conical  teeth.  Rranchio- 
stegal  rays  at  least  15  in  number.  Vertebral  centra  strengthened 
by  a  few  longitudinal  ridges  ;  ribs  very  delicate  and  nearly  straight. 
Pectoral  fins  large  and  pelvic  fins  smaller,  these  opposed  to  the 
hinder  end  of  the  dorsal  or  slightly  behind  it ;  anal  fin  remote, 
small  and  not  much  extended  ;  caudal  fin  deejjly  forked.  17o 
enlarged  scale  at  the  base  of  the  paired  fins ;  no  enlarged  ridge- 
scales. 

The  skeleton  of  this  fish  is  so  delicate  that  it  is  usually  distorted 
in  the  fossils.  It  is  thus  very  difiicult  to  distinguish  the  species, 
which  seem  to  differ  from  each  other  only  in  their  general  propor¬ 
tions  and  in  the  relative  length  of  the  vertebral  centra.

exposed  from  the  left  side,  and  is  a  little  obliquely  crushed 
80  that  the  imperfect  left  mandibular  ramus  is  displaced 
upwards.  The  cranium  is  shown  to  be  elongated  and 
depressed,  with  a  straight  basicranial  axis.  The  pterygo- 
quadrate  arcade  is  shown  to  be  delicate  and  apparently 
toothless  ;  while  the  mandibular  suspensorium  is  almost 
vertical,  though  arched,  and  the  articular  end  of  the 
mandible  is  beneath  the  back  of  the  head.  The  front 
half  of  the  left  facial  region  is  broken  away,  so  that  the 
characteristic  maxilla  of  the  right  side  is  partly  exposed 
from  within,  and  there  seem  to  be  traces  of  a  very  short 
premaxilla  at  its  anterior  end.  Above  the  maxilla  {mx.) 
the  large  antorbital  cheek-plate  is  seen  (a.o.),  partly 
fractured  and  displaying  the  radiating  branches  from  the 
slime-canal.  Below  the  maxilla,  adjoining  the  remains 
of  the  mandible  (d.),  there  is  an  impression  of  the  large 
conical  tooth  at  its  symphysis.  Between  the  mandibular 
rami  the  left  ceratohyal  is  partly  exposed  ;  and  the  series 
of  branchiostegal  rays  is  well  displayed  on  this  side, 
about  15  in  number.  Immediately  behind  the  mandibular 
suspensorium,  the  preoperculum  {p.op.)  is  well  preserved, 
with  a  large  triangular  expansion  at  its  lower  end,  marked 
with  a  few  radiating  branches  of  the  slime-canal ;  but 
the  operculum  and  suboperculum  behind  are  too  much 
crushed  and  fractured  for  recognition.  Just  behind  the 
operculum  there  are  traces  of  the  thickened  anterior 
neural  spines.  Lewis  Coll.

Type.  Parasphenoid  dentition  ;  Eoyal  College  of  Surgeons, 
London. 

The  type  species  of  the  so-called  genus  Pisodus.,  of  large  size, 
the  head  sometimes  attaining  a  length  of  0-3.  Too  imperfectly 
known  to  be  precisely  defined,  but  differing  from  the  sole  existing 
species  in  the  proportions  of  the  cranium  ;  the  distance  from  the 
end  of  the  snout  to  the  anterior  notch  of  the  frontals  being  about 
equal  to  that  from  this  notch  to  the  occiput,  whereas  the  proportion 
of  the  same  measurements  in  the  recent  A.  vulpes  Ms  2 :  3.  Rostrum 
thus  comparatively  large.

P.  9158.  Head  with  opercular  apparatus,  remains  of  the  pectoral 
arch,  and  fragmentary  scales  ;  London  Clay,  Sheppey. 
The  skull  measures  about  0‘3  from  the  occiput  to  the  end 
of  the  snout,  and  the  cheek  has  a  very  similar  aspect  to 
that  of  the  recent  species.  The  specimen  is  crushed 
obliquely,  so  that  the  roof  of  the  cranium  is  shown  entirely 
on  the  left  side  (PI.  IV.  fig.  1  a),  while  the  space  below 
and  behind  the  mandible,  with  some  of  the  branchiostegal 
rays,  appears  on  the  right  side  (fig.  1).  The  whole  of 
the  fossil  is  permeated  with  pyrites,  which  may  decay  and 
eventually  cause  its  destruction.  Of  the  cranium  itself 
only  the  roof  is  exposed,  but  this  is  complete  and  merely 
a  little  fractured  and  in  places  obscured  by  pyrites. 
Behind  the  occiput  the  epiotic  {ep.o.)  is  distinct  on  the 
left  side  ;  the  limits  of  the  squamosals  {sq.),  parietals  {pa.), 
and  frontals  {fr.)  are  sufficiently  clear.  The  postfrontal 
(pt.f.)  is  also  exposed  a  little,  and  the  prefrontal  {pr.f.) 
still  more  on  the  cranial  roof ;  and  the  form  of  the  median 
depression  in  this  roof  is  characteristically  exhibited. 
The  rostrum  is  comparatively  long  and  slender,  too  im¬ 
perfect  for  description  ;  but  the  notch  in  the  anterior 
border  of  the  frontal  is  distinct  on  each  side,  this  beino' 
situated  about  midway  between  the  occiput  and  the  end 
of  the  snout.  Remains  of  the  mandibular  suspensorium 
and  jaws  are  exposed  on  each  side  of  the  fossil ;  and  the 
remarkably  forward  articulation  of  the  mandible  is  well

shown.  The  ossification  of  the  hyomandibular  is  especiall}' 
dense,  as  indicated  by  its  upper  end  (Jim.)  exposed  on 
the  right,  and  by  its  opercular  process  seen  on  the  left 
side.  The  boundaries  of  the  large,  expanded  metapterygoid 
(mpt.)  are  not  completely  shown ;  but  its  long  antero¬ 
inferior  border  is  exhibited  in  contact  with  the  quadrate 
(qu.)  on  each  side  of  the  fossil.  The  latter  element  is 
very  concave  on  its  outer  face  immediately  behind  the 
articular  condyle,  and  sends  backwards  a  long  process  to 
clasp  the  symplectic,  which  is  not  clearly  distinguishable, 
but  seems  to  have  been  long  and  narrow.  An  excavation 
in  the  matrix  on  the  left  side  has  revealed  a  portion 
of  bone  bearing  the  characteristic  PisocZiis-teeth  (.r.), 
which  may  be  entopterygoid.  The  maxilla  (m.u.)  is  frag¬ 
mentary  on  both  sides,  and  the  premaxilla  is  destroyed ;  but 
the  right  mandibular  ramus  is  well-displayed,  showing  the 
suture  between  the  angular  (ag.)  and  dentary  (cl.)  bones. 
The  articular  facette  for  the  quadrate  condyle  is  remarkably 
concave ;  the  bases  of  a  cluster  of  minute  teeth  are  vaguel}’' 
indicated  near  the  symphysis  of  the  dentary.  The  sclerotic 
of  the  eye  (sd.)  is  ossified,  and  there  are  traces  of  cheek- 
plates  on  the  right  side.  The  preoperculum  (x:>.op.)  is 
narrow  and  bent  closely  round  the  hinder  border  of  the 
mandibular  suspensorium.  The  operculum  (op.)  and  sub¬ 
operculum  (s.op>.)  are  much  fractured  on  the  right  side, 
crushed  inwards  on  the  left ;  but  it  is  evident  that  the 
former  is  not  quite  twice  as  deep  as  its  maximum  width, 
while  the  maximum  depth  of  the  latter  equals  somewhat 
more  than  half  its  width.  The  interoperculum  is  not 
definitely  identifiable  ;  but  the  branchiostegal  rays  (hr.) 
are  well  preserved  on  the  right  side  to  the  number  of  nine 
or  ten,  though  probably  others  are  lost  or  obscured  in 
front.  Traces  apparently  of  the  basibranchial  and  robust 
hyoid  bones  project  from  the  matrix  below.  The  pectoral 
arch  and  large  scales  are  too  imperfect  for  description. 
Three  short  and  deep  vertebrae  are  indicated  in  section.

pedicle  scarcely  exceeding  one  third  the  maximum  depth  of  the 
trunk.  Pectoral  fins  comprising  about  14  rays ;  pelvic  fins  with 
7  or  8  rays,  not  shorter  than  the  pectorals,  arising  midway 
between  the  latter  and  the  anal ;  dorsal  fin  with  about  55  rays, 
the  two  or  three  foremost  being  comparatively  short  and  spinous, 
the  first  articulated  ray  the  longest,  and  this  not  exceeding  one  half 
the  depth  of  the  trunk  at  its  insertion  ;  anal  fin  short  and  deep, 
extending  backwards  slightly  beyond  the  dorsal,  and  comprising 
15  rays,  of  which  the  two  foremost  are  comparatively  short  and 
spinous. 

The  appearance  of  a  barbel  below  the  mandible,  observed  in  one 
specimen  by  von  der  Marck  (Zoc.  cit.  1863,  p.  38,  pi.  iv.  fig.  5), 
seems  to  be  deceptive. 

Form.  ^  Loc.  Upper  Cretaceous:  Westphalia. 

P.  3291.  Pine  specimen,  chiefly  in  impression,  nearly  0-5  in  length, 
associated  with  remains  of  smaller  individuals  and  of 
Sardinioides  ;  Sendenhorst.  The  long  and  low  cranium 
can  be  distinguished,  and  the  mandibular  suspensorium 
is  clearly  inclined  forwards,  the  outline  of  the  quadrate 
being  traceable  below  the  orbit.  The  small  gape  of  the 
mouth  is  indicated,  and  there  are  remains  of  a  series  of 
small  hollow  conical  teeth  in  the  upper  jaw.  The  oper¬ 
culum  and  preoperculum  are  shown  in  impression,  and 
there  is  a  series  of  10  branchiostegal  rays  beneath. 
Towards  the  end  of  the  tail  the  impressions  of  the  short 
and  deep  vertebral  centra  exhibit  their  fine  longitudinal 
ridges.  About  twelve  rays  of  one  of  the  pectoral  fins 
are  preserved  not  much  below  the  vertebral  column, 
and  accidentally  turned  forwards.  The  pelvic  fins  com¬ 
prise  comparatively  few  rays,  but  these  must  at  least 
have  equalled  the  pectoral  fin-rays  in  length,  and  they 
are  finely  divided  and  articulated  in  their  distal  half. 
The  dorsal  fin  consists  of  54  rays,  but  those  of  its  anterior 
portion  are  partly  imperfect  and  displaced.  The  anal 
fin  seems  to  comprise  14  or  15  rays,  of  which  the  first 
four  gradually  increase  in  length,  while  the  fifth  is  the 
longest ;  the  two  foremost  rays  are  spinous,  the  next  two 
exhibit  only  close  articulations  towards  the  distal  end,  while 
all  the  others  are  both  divided  and  articulated  distally. 
There  are  numerous  small  fulcral  rays  at  the  base  of  the 
caudal  fin  both  above  and  below.  The  characteristic 
scales  are  only  partly  shown  in  impression ;  but  the

mandible  is  shown  to  be  truncated  at  its  symphysis,  much 
elevated  in  the  coronoid  region.  The  ribs  are  very  slender. 
The  fins,  so  far  as  preserved,  are  as  in  the  last  specimen. 
One  of  the  scales  in  the  dorsal  region  exhibits  the  exten¬ 
sive  overlapped  portion  marked  with  a  few  grooves 
radiating  from  its  centre.  Enniskillen  Coll. 

35034.  A  slightly  larger  specimen  wanting  the  greater  part  of  the

branchiostegal  rays  are  displayed,  and  there  are  remains 
of  the  pectoral  fin  on  the  flank  not  much  below  the 
vertebral  column.  The  two  articulated  but  undivided 
anterior  rays  are  observed  in  the  anal  fin.

that  the  parasphenoid  is  a  slender  toothless  bone,  while 
the  inner  clustered  dentition  is  borne  by  the  long  and 
laminar  entopterygoid.  The  latter  element,  whatever  its 
nature  may  be,  is  only  imperfectly  preserved,  but  the 
hollow  bases  of  the  teeth  are  shown  in  a  patch  extending 
along  its  middle  region,  not  reaching  the  borders.

slenderness  of  the  trunk,  and  are  thus  of  the  form  described  under 
the  name  of  Istieus  gracilis  (L.  Agassiz,  Poiss.  Poss.  vol.  v.  1839-44,

U/'O 


[Bull.  U.S.  Geol.  Surv.  Territ.  vol.  iii.  1877,  p.  584  ^,] 

An  imperfectly  known  genus,  with  an  extended  dorsal  fin  occu¬ 
pying  the  greater  part  of  the  back,  and  a  small  anal  fin  opposed  to 
its  hinder  end.  Teeth  minute  and  clustered  on  the  margin  of  the 
jaws,  also  on  the  parasphenoid  and  other  bones  within  the  mouth. 
About  6  branchiostegal  rays.  Yertebrse  about  80  in  total  number, 
the  centra  deeper  than  long  and  marked  with  fine  longitudinal 
ridges  or  striae.  Scales  elliptical,  not  serrated  or  pectinated.  Hot 
clearly  distinguished  from  Istieus.,  but  apparently  differing  in 
presence  of  teeth  on  parasphenoid  and  clustering  of  marginal  teeth. 

^  The  generic  name  Anogmius  was  originally  given  by  Cope  in  1871  (Proc. 
Amer.  Phil.  Soc.  vol.  xii.  pp.  170,  354)  to  some  detached  vertebra,  specifically 
termed  A.  contractus.  In  1875  he  cnnchided  that  these  vei-tebra  belonged  to 
Pachyrhizodus  (Yert.  Cret.  Form.  West,  p.  220  a).  In  1877  he  used  the  same 
generic  name  again  with  a  new  definition  as  here  given.

Type.  Imperfect  fish  ;  Kansas  University  Museum. 

A  large  species  probably  attaining  a  length  of  about  2"5.  Length 
of  head  with  opercular  apparatus  equalling  about  two  thirds  the 
maximum  depth  of  the  trunk.  Cranial  roof  coarsely  rugose,  and 
snout  tapering  to  an  obtuse  point;  length  of  orbit  contained  three 
times  in  the  length  of  the  cranium  and  twice  in  its  interorbital 
width. 

This  species  seems  to  differ  from  A.  aratus  in  its  relatively  larger 
orbit ;  from  A.  evolutus  in  its  less  numerous  longitudinal  series  of 
mandibular  teeth  ;  and  from  A.  favirostris  in  the  oruamentation  of 
the  cranium  and  its  pointed  snout.

0'65.  The  characteristic  cranium  is  exposed  from  above, 
and  the  cheek-plates  of  the  right  side  are  well  preserved. 
Nearly  40  vertebrae  are  shown  in  the  length  of  trunk 
mentioned,  and  the  ribs  extend  to  the  ventral  border. 
Only  a  few  of  the  supports  of  the  dorsal  fin  remain  ;  but

single  series  ;  minute  styliforni  or  conical  teeth  on  some  of  the 
inner  bones  and  tongue.  Suboperculum  and  interoperculum  rudi¬ 
mentary  or  absent ;  branchiostegal  rays  slender,  about  10  to  20  in 
number,  and  no  gular  plate.  Vertebral  centra  well  ossified,  and 
those  of  the  abdominal  region  with  robust  transverse  processes  for 
the  support  of  the  well-developed  ribs  ;  a  compound  hypural  bone 
at  the  base  of  the  tail.  Intermuscular  bones  present.  Ein-fulcra 
absent ;  fin-rays  more  or  less  divided  and  articulated  distally ; 
dorsal  and  anal  fins  remote  and  more  or  less  extended.  Scales 
thick  and  cycloidal,  mosaic-like  in  structure,  deeply  imbricating. 

The  surviving  members  of  this  family  are  confined  to  the  fresh- 
waters  of  the  tropics.  Osteoglossum  occurs  in  Tropical  America, 
Australia,  and  the  East  Indies  Arapaima  is  eharacteristic  of 
Erazil  and  the  Guyanas ;  while  Beterotis  is  a  Tropical  African 
genus. 

The  only  extinct  genus  referable  with  certainty  to  the  Osteo- 
glossidae  is  Dapedoglossus,  from  the  freshwater  Eocene  of  North 
America.  Bryclicetus^  from  the  marine  London  Clay  of  Sheppey,  is 
also  probably  a  member  of  the  same  family ;  but  its  scales,  so  far 
as  known,  do  not  exhibit  the  characteristic  mosaic-like  structure.

Head  with  opercular  apparatus  attaining  a  length  of  about  0*4. 
Length  of  head  to  preopercular  border  scarcely  exceeding  its 
maximum  depth  at  the  occiput ;  width  of  frontal  region  between 
the  orbits  equalling  about  half  the  total  length  of  the  cranium. 
External  bones  of  cranial  roof  marlied  with  small  pittings,  the 
cheek-plates  and  opercular  apparatus  ornamented  with  radiating 
lines  of  very  fine  tubercles.  Premaxilla  extending  to  the  anterior 
border  of  the  orbit,  at  least  two  thirds  as  long  as  the  more  slender 
maxilla.  Marginal  teeth  ovoid  in  transverse  section,  their  longer 
diameter  at  right  angles  to  the  length  of  the  jaw,  and  all  the 
enamelled  crowns  smooth ;  teeth  of  premaxilla  largest,  teii  in 
number ;  those  of  maxilla  considerably  smaller,  between  20  and 
25  in  number,  decreasing  in  size  backwards,  where  they  become 
comparatively  slender  ;  mandibular  teeth  about  20  in  number, 
nearly  as  large  as  those  of  the  premaxilla  and  scarcely  decreasing 
in  size  behind.  Operculum  nearly  twice  as  deep  as  broad.  Anterior 
scales  closely  ornamented  with  very  small  tubercles  often  fused  into 
short  rugae.

P.  3893.  Imperfect  head  with  opercular  apparatus,  to  be  regarded 
as  the  type  specimen,  partly  shown  of  one  third  the 
natural  size  from  the  left  side  and  from  above  in  PI.  I., 
figs.  1,  la.  The  cranium  is  much  fractured,  the  outer 
surface  of  the  ethmoidal  region,  the  greater  part  of  the 
right  frontal  and  of  the  parieto-occipital  region  being 
broken  away.  The  frontals  (/r.)  are  very  wide  between 
the  orbits,  narrowing  behind,  and  they  are  much 
thickened,  the  outer  surface  preserved  on  the  left  side 
exhibiting  numerous  closely  arranged  pittings.  The 
fossil  has  been  broken  across  immediately  behind  the 
orbit,  thus  causing  a  gap  in  the  left  frontal ;  but  its 
truncated  posterior  margin  is  conspicuous  further  back, 
well  in  advance  of  the  occiput,  and  the  corresponding 
suture  on  the  right  side  is  indicated  by  the  direction  of 
the  growth-lines  of  the  fractured  bone.  The  anterior 
part  of  the  left  parietal  (^a.)  is  shown  to  be  superficially 
pitted  in  the  same  manner  as  the  frontal ;  but  the  region 
beyond  is  obscure  and  more  clearly  observable  in  no, 
P.  157  (PI.  1.  fig.  2).  A  very  large  and  stout  prefrontal 
is  shown  on  the  right  side.  The  orbit  (fig.  1,  orh.)  is 
indicated  far  forwards,  and  the  great  postorbital  region 
is  covered  with  two  cheek -plates,  which  are  very

fragmentary  on  both  sides  of  the  fossil.  The  upper  post¬ 
orbital  (s.o.  1)  is  somewhat  the  smaller,  and  exhibits  a 
series  of  clefts  in  its  hinder  border  ;  both  bear  traces  of 
the  characteristic  fine  tubercular  ornament.  The  ossified 
sclerotic  is  seen  on  the  right  side.  The  jaws  and  teeth 
are  imperfect,  but  best  preserved  on  the  left  (fig.  1).  The 
premaxilla  {pmx.')  is  observed  to  extend  to  the  front 
border  of  the  orbit ;  while  above  the  hinder  half  of  the 
comparatively  slender  maxilla  {moo.)  there  seems  to  be  a 
small  supramaxilla  Most  of  the  teeth  are 

broken  and  display  an  internal  cavity  ;  but  a  few  of  those 
of  the  mandible  and  several  of  those  of  the  maxilla  are 
complete,  with  the  smooth  enamelled  crown  pointed  and 
a  little  curved  inwards  at  the  apex.  The  wide  expansion 
of  the  angle  of  the  preoperculum  is  observable  on  the 
left  behind  the  portion  of  the  fossil  figured,  and  the  form 
of  the  large  operculum  can  be  dimly  perceived  on  both 
sides.  The  large  and  deepl}"  imbricating  scales,  of  which 
one  from  the  right  side  is  shown  of  the  natural  size  in 
fig.  1  6,  are  externally  ornamented  with  fine  tubercles 
tending  to  arrangement  in  radiating  lines  ;  and  there  is 
no  appearance  either  of  a  mosaic  or  reticulated  structure 
even  when  this  superficial  layer  of  ornament  is  removed.

form,  thickening,  and  superficially  pitted  character  as 
before  ;  their  truncated  hinder  margin  is  also  distinct  in 
the  same  position  immediately  behind  the  orbit.  The 
anterior  thickened  and  pitted  portion  of  each  parietal  is 
shown  to  be  about  as  broad  as  long,  and  there  are  traces 
of  the  long,  narrow  squamosal  on  either  side ;  but  the 
occipital  region  is  crushed  and  obscured.  Some  of  the 
teeth  are  well  shown  on  the  left  side.  There  are  also 
characteristic  remains  of  the  squamation  ;  and  the  right 
supraclavicle  is  shown  to  be  very  long  and  narrow.

excessively  long  and  narrow.  There  are  remains  of  a 
short  and  broad  ethmoid  in  front  of  the  frontals  (/r.)  not 
shown  in  the  figure.  The  extent  of  the  premaxilla  {'pmx.) 
is  indicated  on  both  sides,  and  it  seems  to  have  borne 
10  teeth.  The  best  preserved  tooth,  at  the  hinder  end 
of  the  left  premaxilla,  is  shown  of  the  natural  size  in 
fig.  2  h.  The  two  postorhital  cheek-plates  are  exhibited, 
the  lower  (s.o.2)  much  the  largest  as  usual.  The  charac¬ 
teristic  fine  tubercular  ornament  is  observed  on  the 
operculum  {op.)  and  also  slightly  on  the  upper  cheek-plate 
of  the  left  side.  Fourteen  branchiostegal  rays  are 
preserved  on  the  right.  There  are  also  some  rays  of  the 
right  pectoral  fin  {pet.),  the  foremost  being  comparatively 
stout.  Purchased,  1880. 

P.  638.  A  pyritised  decaying  specimen,  labelled  by  Agassiz  as

It  exhibits  the  large  robust  prefrontal  bone  on  the  right 
side.  The  maxilla  is  also  well  shown,  with  its  charac¬ 
teristic  dentition  and  a  comparatively  delicate  small 
expansion  behind.  The  preoperculum  is  evidently 
expanded  at  the  angle,  and  there  are  remains  of  about 
14  pairs  of  slender  branchiostegal  rays.  Egerton  Coll,

shown  to  be  somewhat  more  than  half  as  broad  as  deep  ; 
while  both  this  and  the  left  lower  postorbital  plate 
exhibit  remains  of  the  superficial  ornament  of  radiating 
tuberculated  lines.  The  number  of  branchiostegal  rays

the  present  writer  loc.  cif.,  exhibits  the  broader  end  of  a  dental 
plate  much  like  that  just  defined,  near  the  remains  of  the  mandible. 
In  the  same  specimen  a  concave  dental  plate  of  similar  structure  is 
clearly  observed  fixed  to  the  base  of  the  cranium.  This  imperfect 
fossil  and  another  mentioned  below  have  thus  been  provisionally 
ascribed  to  Pletliodus  obloyigus,  and  exhibit  the  cranial  characters 
noted  in  the  diagnosis  of  the  genus  given  above.

A  provisional  name  given  to  fragmentary  remains  of  a  genus  of 
fishes,  which  has  not  yet  been  clearly  distinguished  from  Cliiro- 
centrites.  Supraoccipital  bone  bearing  a  conspicuous  median 
longitudinal  cj'est ;  premaxillse  short  and  deep.  Teeth  confined 
exclusively  to  the  premaxillary,  maxillary,  and  dentary  bones,  all 
hollow,  snbcylindric  or  moderately  compressed,  but  destitute  of 
sharp  or  serrated  edges,  and  lodged  in  deep  sockets ;  very  irregular 
in  size,  those  of  the  premaxilla,  middle  of  maxilla,  and  anterior  end 
of  dentaiy  relatively  large.  Successional  teeth  formed  directly 
beneath  the  functional  teeth,  and  no  nutritive  foramina  on  the 
inner  face  of  the  jaw  below  the  alveolar  border.  All  the  vertebral 
centra,  except  a  few  immediately  behind  the  bead,  exhibiting  two 
deep,  longitudinally-extended  pits  on  each  side.  Both  paired  fins 
with  few  broad  and  stout  rays,  which  are  very  finely  articulated  and 
divided  quite  at  the  distal  end.

the  caudal  fin.  Teeth  smooth,  stout,  and  nearly  circular  in  trans¬ 
verse  section,  those  of  the  mandible  slightly  larger  than  those  of 
the  upper  jaw;  oral  border  of  maxilla  nearly  straight,  that  of  the 
dentary  feebly  sinuous.  Vertebral  centra  as  deep  as  long,  about 
25  in  the  abdominal,  35  in  the  cauaal  region.  Dorsal  fin  opposite 
the  middle  of  the  anal  fin,  which  comprises  somewhat  more  than 
30  rays,  the  foremost  seven  or  eight  closely  adpressed  and  forming 
the  lobe. 

The  unique  original  specimen  of  this  species  in  the  Geneva 
Museum  is  preserved  in  counterpart ;  and  although  there  is^a 
fracture  across  the  unusually  short  abdominal  region,  it  does  not 
appear  to  have  lost  any  intervening  portion.  The  skull  is  im¬ 
perfect  behind,  but  is  shown  to  have  been  wide  between  the  orbits, 
with  a  very  robust  prefrontal  (ectethmoidal)  ossification.  The 
premaxilla  is  not  preserved  ;  and  neither  the  fossil  nor  its  counter¬ 
part  now  exhibits  the  anterior  upper  tooth-bearing  fragment  of 
bone  represented  in  Pictet’s  figure.  The  characteristic  maxilla  is 
distinct,  fractured  across  its  anterior  half  and  not  intelligibly 
shown  in  the  figure.  The  sinuous  contour  of  the  oral  border  of 
the  mandible  is  also  exaggerated  in  the  latter ;  and  the  fossil  is 
not  sufficiently  well  preserved  to  determine  whether  or  not  the 
mandible  really  tapers  to  the  symphysis  so  much  as  appearances 
suggest.  There  are  remains  of  thin  cheek-plates  ;  and  one  pre¬ 
operculum  is  displaced  beneath  the  opercular  region.  A  few  traces 
of  delicate  branchiostegal  rays  occur  below  the  mandible.  The 
so-called  anterior  dorsal  fin  of  Pictet  is  a  false  appearance  due  to 
the  displacement  of  some  neural  spines,  where  the  squamation  has 
also  been  disturbed  (as  noted  by  Bassani,  he.  dt.).

P.  8633.  The  type  specimen,  being  the  head  and  part  of  the  abdo¬ 
minal  region  exposed  from  the  right  side,  shown  of  the 
natural  size  in  PL  VIII.  Gault,  Polkestone.  The 
anterior  ethmoidal  end  of  the  cranium  is  slender  and 
pointed,  while  the  supraoccipital  (s.ocr.)  rises  as  usual 
into  a  rounded  median  crest.  The  ectethmoid  or  pre¬ 
frontal  (pr./.)  is  relatively  large  and  stout,  with  the 
usual  flattened  facette  for  the  articulation  of  the  anterior 
thickened  end  of  the  palatine  The  premaxillae 

(pmi\)  are  deeper  than  long,  and  meet  in  the  middle  line 
in  front  of  the  ethmoid.  Their  teeth  are  very  small,  but 
must  have  been  slightly  larger  than  those  of  the  maxilla, 
which  are  quite  minute.  The  maxilla  (nix.)  displays  its 
articulation  with  the  palatine  in  front,  and  is  overlapped 
behind  by  the  cheek-plates  :  its  oral  margin  is  excavated 
just  behind  its  anterior  end,  hut  is  strongly  convex 
further  back.  Its  minute  teeth  are  fi.xed  just  within  the 
rugose  border.  The  mandible  is  remarkably  deep,  and 
the  symphysial  end  of  the  dentary  (cl.)  slopes  slightly 
backwards  and  downwards.  Its  oral  margin  is  only 
exposed  in  front,  where  the  slender,  styliform  teeth  are 
considerably  larger  than  any  shown  in  the  upper  jaw. 
There  are  remains  of  large,  smooth,  suborbital  cheek- 
plates  (s.o.) ;  and  the  sclerotic  of  the  eye  {scl.)  is  well 
ossified.  The  preoperculum  (p.op.)  forms  a  great  tri¬ 
angular  expansion,  rather  thin  and  nearly  smooth,  with 
a  slightly  thickened  anterior  border.  The  operculum  (opl) 
and  other  plates  are  fragmentary.  Some  of  the  anterior 
vertebral  centra  are  slightly  longer  than  deep,  and  display 
the  characteristic  pittings.  The  bases  of  some  of  the

[Plate  IX.  fig.  6.] 

Type.  Imperfect  skull ;  British  Museum. 

A  small  species  known  only  by  remains  of  the  head.  Oral 
border  of  maxilla  and  dentary  nearly  straight ;  depth  of  dentary  at 
symphysis  not  exceeding  one  quarter  the  total  length  of  the  man¬ 
dibular  ramus.  Teeth  very  slender  and  smooth,  with  apex  slightly 
curved  inwards. 

Form.  Log.  Turonian  and  (?)  Albiau  :  Kent. 

49054.  Type  specimen,  an  imperfect  head  shown  of  the  natural 
size  in  PI.  IX.  fig.  6  ;  Lower  Chalk,  Burham,  Kent.  The 
fossil  exhibits  the  superior  and  right  lateral  aspects  of 
the  head,  but  is  transversely  fractured  and  partially  dis¬ 
placed  at  the  front  border  of  the  orbit.  The  cranial  roof 
is  narrow,  exhibiting  the  usual  median  crest  behind,  and 
the  frontal  bone  of  the  right  side  raised  into  a  longi¬ 
tudinal  ridge.  The  frontals  seem  to  extend  backwards  as 
far  as  the  hinder  border  of  the  orbit,  and  the  very  small 
median  ethmoid  is  conspicuous  at  the  end  of  the  snout. 
None  of  the  bones  are  externally  ornamented.  The  ver}’ 
large  size  of  the  eye  is  indicated  by  fragments  of  the 
ossified  sclerotic  {scl.) ;  immediately  behind  this  are  the 
remains  of  the  thin  cheek-plates  (5.0.),  with  traces  of  the 
slime-canal  which  seems  to  have  had  radiating  branches  ; 
while  in  front  may  be  observed  the  robust  prefrontal 
(ptr.f.),  with  its  flattened  inferior  facette  for  the  palatine. 
The  maxilla  (mau)  is  long  and  slender,  but  much  fractured, 
so  that  its  anterior  end  is  displaced  and  only  three  of  the 
slender  teeth  remain  ;  a  facette  postero-superiorly  shows 
the  extent  of  overlap  of  a  supramaxillary  bone.  The 
general  proportions  of  the  mandible  are  indicated,  but 
the  anterior  end  of  this  is  also  fractured.  At  the  sym¬ 
physis  and  behind  the  fracture  a  few  of  the  characteristic 
teeth  are  preserved.  The  outer  surface  of  the  dentaiy  (d.) 
3s  smooth  and  only  gently  undulating,  without  any  sharp 
longitudinal  ridge.  The  preoperculum  {p).op.)  is  shown 
to  be  much  expanded,  with  thickened  anterior  margin, 
and  the  usual  radiating  branches  of  the  sensory  canal.

Type.  Anterior  portion  of  fisb ;  Geneva  Huseum. 

A  species  attaining  a  length  of  about  0*6,  known  b}’  the  greater 
part  of  the  fish,  differing  from  Chirocentrites  and  resembling  Iclithy- 
odectes  in  the  characters  of  the  dentition.  Haximum  depth  of 
trunk  equalling  somewhat  more  than  one  quarter  of  its  length 
from  the  pectoral  arch  to  the  base  of  the  caudal  fin.  Oral  border 
of  maxilla  gently  sinuous,  concave  in  its  anterior  half ;  teeth  of 
maxilla  and  dentary  approximately  equal  in  size,  all  very  slender, 
straight,  and  closely  arranged  ;  premaxillary  teeth  somewhat 
stouter  and  more  sharply  pointed,  the  foremost  larger  than  the 
others.  Other  characters  as  in  Chirocentrites  coroninii.

39238.  More  imperfect  remains  of  a  smaller  fish;  Hakel.  The 
anterior  half  of  the  maxilla  is  well  shown,  deepened  at 
its  robust  palatine  articulation.  Beneath  it  is  part  of 
the  mandible,  half  only  in  impression,  with  traces  of 
teeth  like  those  of  the  maxilla  and  possibly  (though 
doubtfully)  with  a  few  slightly  larger  teeth.  Very 
slender  branchiostegal  rays  are  also  seen  beneath  the 
remains  of  the  mandible,  and  the  series  is  continued  by 
larger  rays  beneath  the  opercular  apparatus  :  these  cannot 
have  been  less  than  20  in  number.  The  extremities  of 
some  stout  pelvic  and  anal  fin-rays  are  observed  chiefly 
in  impression.  Tristram  Coll.

an  indication  of  a  slightly  enlarged  anterior  tooth  followed 
by  two  smaller  teeth.  The  broad,  sharply-angulated  pre- 
operculnm,  with  thickened  anterior  border  and  radiating 
markings,  can  be  distinguished  at  the  back  of  the  head. 
The  scattered  pectoral  fin-rays  are  remarkabh^  robust ; 
and  the  two  examples  apparently  of  the  foremost  ra}’ 
exhibit  much  complexity  at  the  divided  distal  end.  At 
this  end  the  ray  exhibits  longitudinal  clefts  for  the 
greater  part  of  its  width,  but  numerous  oblique  sutures 
in  its  front  portion.  Lewis  Coll.

centra  at  least  as  long  as  deep,  each  impressed  with  two  lateral 
pits  ;  neural  and  haemal  spines  of  tail  much  depressed  and  imbri¬ 
cating.  Paired  fins  small,  with  very  stout  rays ;  dorsal  fin  some¬ 
what  longer  than  deep,  opposed  to  the  pelvic  pair;  [anal  fin  un¬ 
known];  caudal  fin  deeply  cleft.  Scales  very  large,  mostly  deeper 
than  broad ;  ornamented  in  their  exposed  portion  with  numerous 
small  pittings,  and  marked  in  their  covered  portion  by  a  few  con¬ 
spicuous  radiating  grooves. 

This  incomplete  definition  is  based  upon  the  type  specimen  of 
Ancedopogon  teniddens  in  the  II.S.  jSTational  Museum,  several  speci¬ 
mens  of  the  same  species  in  the  Brazilian  hTational  Museum  at  Bio 
de  Janeiro,  and  the  small  series  of  fragments  from  Brazil  catalogued 
below.  This  fish  would  be  referred  to  the  genus  Icfiihyodectes  if 
the  dorsal  fin  were  not  so  far  forwards,  as  shown  in  a  specimen  in 
the  Brazilian  I^ational  Museum.  The  detached  scales  described 
from  other  localities  under  the  name  of  Cladocyclus  are  doubtfully 
ascribed  to  the  same  genus.  Most  of  them  probably  belong  to 
species  of  Ichtliyodectes  and  Portlieus.  Scales  much  resembling 
those  named  C.  occidentcdis  are  shown  on  a  specimen  of  Ichtliyodectes 
in  the  Kansas  IJniversity  Museum.

physial  bone  in  the  mandible.  Vertebrae  as  in  Ichtliyodectes  and 
Chirocentrites. 

The  identity  of  the  so-called  Daptinus  with  this  genus  was  deter¬ 
mined  by  Cope  after  an  examination  of  the  type  specimen  of 
Saurodon  leanus  (Bull.  F.S.  Geol.  Surv.  Territ.  vol.  iii.  1877,

Dental  crowns  smooth,^  as  deep  as  broad,  with  the  sharp  edges 
convex  or  slightly  sinuous  and  the  apex  sometimes  curved  back¬ 
wards  ;  about  9  or  10  dental  alveoli  in  the  premaxiUa,  about  36  in 
the  maxilla,  and  about  42  in  the  dentary.  Length  of  oral  border 
of  premaxilla  about  three  quarters  its  depth ;  length  of  oral  border

INCERT^  SEDIS  (?  efiiitOeENTPTD.E). 

Genus  TOMOGNATHUS,  Dixon. 

[Geol.  Sussex,  1850,  p.  376.] 

A  genus  known  only  by  the  head,  which  is  short  and  deep  and 
much  laterally  compressed,  with  excessively  shortened  rostral  region. 
Skull  with  a  delicate  median  occipital  crest  extending  as  far  for¬ 
wards  as  the  back  of  the  large  orbit ;  cleft  of  the  mouth  horizontal, 
also  terminating  at  a  point  opposite  the  hinder  border  of  the  orbit ; 
dentigerous  half  of  mandible  slender,  its  hinder  half  deepened. 
Teeth  hollow  and  conical,  enamelled  only  in  their  distal  half,  and 
directly  fused  with  the  jaw,  not  implanted  in  sockets  ;  those  of  the 
premaxilla  and  the  symphysial  end  of  the  dentary  much  enlarged, 
while  those  of  the  maxilla  are  relatively  small,  decreasing  in  size

Tgpe.  Imperfect  skull,  with  jaws. 

The  type  species,  the  head  with  opercular  apparatus  attaining  a 
length  of  0’07.-  Orbit  occupying  nearly  half  the  total  length  of  the 
head,  the  maxilla  nearly  three  and  a  half  times  as  long  as  its  maxi¬ 
mum  depth,  and  the  mandibular  ramus  a  little  more  than  three 
times  as  long  as  its  maximum  depth.  The  robust  jiremaxillce  fused 
together,  and  each  bearing  four  large  teeth  gradually  decreasing  in 
size  from  the  middle  line  to  the  side ;  these  teeth  scarcely  tumid  at 
the  base,  nearly  straight,  enamelled  and  faintly  fluted  in  their 
distal  half.  None  of  the  maxillary  teeth  more  than  half  as  large 
as  the  latter,  very  slender,  and  rapidly  becoming  small  in  the  very 
close  series  behind  about  eight  teeth  in  the  ectopterygoid  series  as 
large  as  the  anterior  maxillary  teeth.  Outer  mandibular  teeth 
closely  similar  to  those  of  the  premaxilla,  but  those  at  the  sym¬ 
physis  a  little  more  tumid  at  the  base  and  incurved  at  the  apex ; 
the  foremost  tooth  relatively  small,  the  next  three  the  largest,  then 
another  small  one  as  the  first  of  a  diminishing  series  of  about  six  to 
eight  teeth.  Width  of  operculum  nearly  equalling  one  quarter  the 
length  of  the  skull;  suboperculum  wider  than  deep;  both  destitute 
of  superficial  ornament. 

Form.  Log.  Turonian  Kent,  Sussex,  and  Surrey.

ACTINOPTERTGII. 


An  extinct  family,  of  the  Cretaceous  period,  known  only  by  two 
genera,  one  with  ctenoid  scales  (Ctenothrissa)^  the  other  with  cycloid 
scales  (Aulolepis). 

Genus  CTENOTHRISSA,  A.  S.  Woodward. 

[Ann.  Mag.  Nat.  Hist.  (7)  vol.  iii.  1899,  p.  490.] 

Head  large,  trunk  fusiform  and  laterally  compressed.  Maxilla 
robust  and  arched  ;  mandible  a  little  prominent,  and  gape  not 
extending  behind  the  middle  of  the  large  orbit.  Yertebrse  30  to 
40  in  number,  half  being  caudal.  Dorsal  fin  much  deepened, 
occupying  about  half  of  the  back  ;  anal  fin  small ;  caudal  fin  deeply 
forked.  Scales  pectinated,  large  and  regularly  arranged,  none 
enlarged  or  thickened,  and  no  ventral  ridge-scales ;  lateral  line 
conspicuous.

Type.  Imperfect  fish  ;  Geneva  Museum. 

The  type  species,  attaining  a  length  of  about  0*07.  Length  of 
head  with  opercular  apparatus  approximately  equal  to  the  maxi¬ 
mum  depth  of  the  trunk  and  contained  about  one  and  a  half  times 
in  the  length  from  the  pectoral  arch  to  the  base  of  the  caudal  fin. 
Vertebrae  30  in  number.  Pectoral  fins  about  half  as  long  as  the 
pelvic  pair,  which  are  inserted  beneath  the  former  and  comprise  8 
stout  rays,  the  foremost  only  articulated  distally,  the  others  both 
di’  ided  and  articulated  distally,  the  longest  when  adpressed  to  the 
trunk  reaching  the  anal  fin  ;  dorsal  fin  comprising  from  18  to  20 
rays,  none  spinous,  about  the  sixth  being  the  longest,  and  its  length 
equalling  two  thirds  the  depth  of  the  trunk  at  its  insertion ;  two 
thirds  of  the  dorsal  fin  situated  in  the  anterior  half  of  the  back, 
and  the  anal  fin,  with  13  or  14  rays,  arising  opposite  its  posterior 
third ;  the  articulations  of  all  the  fin-ravs  rather  distant.  Scales 
very  finely  pectinated.

(1887),  p.  508,  pi.  xxvii.  fig.  4  ;  Hakel.  The  cranium  is 
so  much  broken  and  displaced  that  the  frontal  bones  are

exposed  from  above.  The  narrowness  of  the  opercular 
apparatus  and  the  form  of  the  preoperculum  are  well 
shown  in  impression.  The  vertebrae  cannot  be  distinctly 
counted,  but  they  do  not  appear  to  exceed  30  in  number. 
Xot  more  than  8  rays  can  be  observed  in  either  of  the 
pelvic  fins,  which  are  crushed  together.  The  dorsal  fin 
shows  at  least  18  rays,  and  the  foremost,  though  un¬ 
divided,  can  scarcely  be  described  as  spines.  The  posterior 
ra3\s  of  the  anal  fin  do  not  extend  any  nearer  to  the 
caudal  fin  than  in  the  tj’pical  C.  vex'dlifer.  Lewis  ColL

Type.  Imperfect  fish  ;  British  Museum. 

A  robust  species,  attaining  a  length  of  about  0*25.  Length  of 
head  with  opercular  apparatus  somewhat  less  than  the  maximum 
depth  of  the  trunk  and  contained  about  twice  in  the  length  from 
the  pectoral  arch  to  the  base  of  the  caudal  fin.  Head  and  oper¬ 
cular  apparatus  with  a  fine  rugose  ornament;  the  supramaxillaries 
remarkably  short  and  deep  ;  operculum  about  twice  as  deep  as 
broad.  YertebrEe  approximately  40  in  number.  Pelvic  fins  with  7 
or  8  stout  rays  which,  when  adpressed  to  the  trunk,  extend  to  the 
anal  fin ;  dorsal  fin  arising  opposite  a  point  just  behind  the  inser¬ 
tion  of  the  pelvic  fins  ;  anal  fin,  with  at  least  12  rays,  arising 
opposite  the  hinder  end  of  the  dorsal  fin.  Scales  moderately  large ; 
lateral  line  extending  along  the  ninth  series  above  that  which  forms 
the  ventral  border  of  the  flank ;  all  the  scales  very  finely  serrated 
and  deeply  pectinated,  those  of  the  anterior  portion  of  the  fish  also 
slightly  rugose  or  tuberculated.

behind.  The  pelvic  fins  are  crushed  together,  thus  giving 
a  false  impression  of  the  number  of  rays  ;  and  there  is  no 
evidence  of  an  anterior  spine.  The  scales  seem  to  be 
somewhat  abraded,  and  most  of  those  preserved  have  a 
smooth  posterior  border;  but  a  few  behind  the  pelvic  fins 
seem  to  exhibit  traces  of  an  original  very  fine  pectination.

P.  4747.  Pine  specimen  displaying  all  the  principal  characters  of 
the  genus  and  species,  shown  of  the  natural  size  in 
PI.  VI.  fig.  1  ;  Hakel,  Mt.  Lebanon.  The  fish  is  exhibited 
in  direct  side-view,  with  the  cheek  and  U2:)per  jaw  crushed 

a  little  forwards.  The  form  of  the  relativelv  small 

%/ 

cranium  is  distinct,  and  the  delicate  parasphenoid  is 
gently  bent  upwards  at  the  anterior  end  of  the  otic  region. 
Eemains  of  the  large  pterygo-quadrate  arcade  occur 
beneath  the  cranium,  the  articular  end  of  the  quadrate 
(^M.)  for  the  support  of  the  mandible  being  directly  under 
the  anterior  margin  of  the  orbit.  The  premaxillae 
are  shown,  one  being  imperfect,  the  other  onU  in 
impression  ;  and  these  are  proved  to  be  longer  than  deep, 
though  small  compared  with  the  maxillae.  One  maxilla 
(apparently  the  left  viewed  from  within)  is  especially  well 
preserved  (ai.r.),  exhibiting  its  convex  oral  border  and  a 
remarkably  large  anterior  inwardly-directed  process ;  but 
?io  teeth  are  distinctly  seen,  merely  some  fine  transverse 
striations  on  the  oral  margin  in  its  hinder  half.  Above 
the  maxilla  are  remains  of  the  two  characteristic  supra- 
maxillary  bones.  The  mandible  (cZ.)  is  remarkably  short 
and  deep,  partly  obscured  by  fragments  of  cheek-plates  ; 
scarcely  more  than  the  anterior  third  of  its  upjier  margin 
can  have  entered  the  cleft  of  the  mouth.  Postero-

inferiorly  the  head  is  bordered  by  the  great  expanded 
preoperculum  (p.op.),  which  has  a  thickened  anterior 
margin  and  is  nearly  smooth,  marked  only  very  slightly 
by  the  delicate  radiating  branches  of  the  slime-canal. 
The  right  ceratohyal  {cli.)  and  hypohyal  are  crushed  a 
little  downwards,  the  former  bearing  nine  branchiostegal 
rays  (&r.),  which  are  laminar  in  shape  but  contract  to  a 
point  as  they  curve  to  their  insertion.  The  operculum 
(oj?.)  is  imperfect,  but  clearly  deep  and  narrow  ;  the  sub¬ 
operculum  is  not  recognizable.  The  vertebrae  are  all 
imperfect,  but  there  are  distinct  indications  of  the  slight 
longitudinal  ridges  by  which  the  centra  are  strengthened. 
The  ribs  are  as  stout  as  in  Clupea^  and  the  neural  spines  in 
front  of  the  dorsal  fin  are  not  fused  with  their  respective 
arches.  Intermuscular  bones  occur  throughout  the  trunk 
both  above  and  below  the  vertebral  column.  The  clavicle 
and  supraclavicle  are  shown  to  be  slender;  the  postclavicle 
(s.op.)  is  relatively  large.  The  rays  of  the  paired  fins  are 
observed  to  be  relatively  as  robust  as  those  of  the  caudal ; 
the  rays  of  the  dorsal  fin  are  more  slender.  The  detached 
anal  fin-rays  are  distinct  and  shown  to  be  very  closely 
divided  and  articulated  ;  their  supports  are  connected  with 
each  other  by  a  process  extended  along  the  ventral  border 
of  the  tail.  The  squamation  is  well  displayed  in  part,  and 
the  ventral  ridge- scales  ajDpear  to  be  destitute  of  serrations.

suboperculum  deep  and  narrow ;  branchiostegal  raj's  about  10  in 
number.  Vertebrae  from  31  to  46  in  number,  the  centra  much 
constricted  and  strengthened  with  few  longitudinal  ridges.  Paired 
fins  of  moderate  or  small  size,  the  pectorals  inserted  aboye  the 
yentral  border,  the  pelyic  pair  either  in  adyance  of  the  dorsal  or 
opposite  its  most  anterior  rays  ;  dorsal  fin  arising  in  front  of  the 
middle  point  of  the  back,  neyer  more  but  usually  less  extended  than 
the  anal,  which  is  longer  than  deep  ;  caudal  fin  deeply  forked  ;  no 
fin-rays  excessiyely  elongated.  Scales  small  or  of  moderate  size, 
not  pectinated ;  a  series  of  thickened  ridge-scales,  not  produced 
into  lateral  wings,  extending  along  the  back  between  the  occiput 
and  the  dorsal  fin  ;  a  series  of  larger  thickened  ridge-scales,  with 
lateral  wings,  similarly  extending  along  the  yentral  border  from  the 
pectoral  arch  to  the  origin  of  the  anal  fin. 

This  genus  is  represented  at  the  present  day  by  species  from  the

Type.  Nearly  complete  fish. 

A  small  species,  attaining  a  length  of  about  0'12,  the  caudal 
region  comparatively  stout  and  slightly  longer  than  the  abdominal 
region.  Dorsal  region  not  much  elevated.  Length  of  head  with 
opercular  apparatus  nearly  equalhng  the  maximum  depth  of  the 
abdominal  region,  which  is  contained  about  two  and  a  half  times  in 
the  total  length  of  the  fish  to  the  base  of  the  caudal  fin.  Abdominal 
vertebrae  16,  caudals  18  in  number.  Each  pectoral  fin  with  about 
12  rays,  the  longest  not  reaching  the  pelvic  pair,  which  arises 
nearly  midway  between  the  pectorals  and  the  anal,  opposite  the 
origin  of  the  dorsal ;  dorsal  fin  longer  than  deep,  with  17  rays,, 
occupying  nearly  the  middle  third  of  the  back ;  anal  fin  much 
extended,  with  29  rays,  arising  in  advance  of  the  hinder  end  of  the- 
dorsal.  Dorsal  scutes  about  twnce  as  broad  as  long,  wuth  a  longi¬ 
tudinal  median  keel;  ventral  ridge-scales  about  25  in  number,  not 
serrated,  decreasing  in  size  backwards. 

The  fossilised  examples  of  this  fish  are  very  variously  distorted, 
and  it  is  thus  difficult  to  determine  its  precise  form  and  proportions. 
The  so-called  Clupea  larteti.,  Sauvage,  from  Hakel,  Mt.  Lebanon,  is 
probably  a  specimen  elongated  by  distortion.  It  is  stated  by 
Sauvage  to  have  38  vertebrae,  but  only  33  are  shown  in  his  figure 
of  the  type  specimen.

Type.  Imperfect  fish;  Paris  Museum  of  Natural  History. 

A  species  of  slender  proportions,  attaining  a  length  of  about  0'25, 
but  not  satisfactorily  definable  on  account  of  imperfect  preservation. 
Abdominal  vertebrae  about  22,  caudals  24  in  number.  Length  of 
head  with  opercular  apparatus  somewhat  exceeding  the  maximum 
depth  of  the  trunk  and  equalling  one  quarter  of  the  total  length  to 
the  base  of  the  caudal  fin.  Dorsal  fin  with  about  12  rays,  not 
extending  behind  quite  so  far  as  the  middle  point  between  the 
occiput  and  the  base  of  the  caudal  fin  ;  pelvic  fins  arising  opposite 
the  middle  of  the  dorsal,  midway  between  the  pectorals  and  the 
anal ;  the  latter  fin  relatively  small. 

If  the  specimens  labelled  Clupea  megaptera  by  Agassiz  are 
correctly  determined,  the  type  specimen  described  by  de  Blainville 
under  this  name  must  have  been  somewhat  distorted  and  with 
incomplete  dorsal  fin.

A  species  attaining  a  length  of  about  OM,  perhaps  sometimes 
larger.  Length  of  head  with  opercular  apparatus  somewhat 
exceeding  the  maximum  depth  of  the  trunk  and  equalling  one 
quarter  of  the  total  length  of  the  fish.  Yertebrse  approximately  45 
in  number,  about  half  abdominal,  half  caudal.  Dorsal  fin  slightly 
deeper  than  long,  with  from  12  to  14  rays,  and  its  origin  less  than 
twice  as  remote  from  the  base  of  the  caudal  fin  as  from  the  occiput ; 
pelvic  fins  arising  opposite  the  anterior  half  of  the  dorsal,  midway 
between  the  pectorals  and  the  anal ;  the  latter  fin  less  elevated  than 
the  dorsal,  with  about  20  rays  and  extending  close  to  the  caudal. 
Yentral  ridge-scales  with  very  prominent  backwardly- directed  point, 
about  22  in  number.

(after  H.  von  Meyer,  Palaeontogr.  vol.  ii.  1851,  p.  93,  pi.  xiv.  fig.  1), 
but  their  comparatively  deepened  form  seems  to  be  due  to  distortion

Type.  Imperfect  fish  ;  Paris  Museum  of  Natural  History. 

A  species  attaining  a  length  of  about  0*3.  Head  with  opercular 
apparatus  large,  its  length  exceeding  the  maximum  depth  of  the 
trunk  and  contained  about  twice  in  the  length  from  the  pectoral  arch 
to  the  base  of  the  caudal  fin.  Yertebrse  about  30  in  the  abdominal, 
25  in  the  caudal  region.  Dorsal  fin,  with  about  18  rays,  almost 
completely  in  advance  of  the  middle  point  between  the  occiput  and 
the  caudal  fin ;  pelvic  fins  inserted  opposite  the  middle  of  the 
dorsal ;  anal  fin  with  14  or  15  rays.  Scales  relatively  large, 
sometimes  pitted  in  their  exposed  portion. 

All  the  known  examples  of  this  species  are  distorted  and  frag¬ 
mentary  ;  hence  diflferences  between  various  specimens  which  have 
been  supposed  to  represent  four  distinct  species.  The  name  Clugjea 
elongata  cannot  be  used,  having  been  employed  by  Lesueur  in  1817 
for  an  existing  fish  of  another  species.

termination,  but  seems  to  represent  a  member  of  the  Enchodontidae

Foss.  vol.  V.  pt.  ii.  1844,  p.  120)  to  an  unknown  fish  from  the  neigh¬ 
bourhood  of  Bingen.  Clupea  laiuleyi,  C.  m enegliinii^ and  C.  sauyagep^-^ 
are  also  merely  names  for  undetermined  fishes  from  the  Upper 
Miocene  of  Gabbro,  Tuscany  (de  Bosniaski,  Atti  Soc.  Tosc. — Proc. 

Yerb.  vol.  i.  1878,  p.  xix). 

The  existing  genus  Chatoessus  (Cuvier,  Begne  Animal,  ed.  2, 
vol.  ii.  1829,  p.  320)  has  been  supposed  to  occur  in  the  Upper 
Miocene  of  Podsused,  Croatia  (Chatoessus  humilis^  C.  hrevis,  and 
C.  tenuis,  F.  Steindachner,  Sitzungsb.  k.  Akad.  Wiss.,  math.- 
naturw.  Cl.  vol.  xxxviii.  1859,  pp.  782-788,  pi.  hi.).  The  fishes 
thus  named,  however,  are  claimed  by  Kramberger  to  belong  merely 
to  a  species  of  Clupea  characterised  by  the  elongation  of  the  hinder-

referred  the  portion  of  the  trunk  of  a  fish  described  as 


Recent  fishes  distinguished  from  the  Clupeidae  by  the  presence  of 
an  adipose  dorsal  fin*  and  the  incompleteness  of  the  oviducts ;  also 
by  the  normal  overlapping  of  the  postclavicular  plate  by  the  clavicle. 
The  extinct  genera  not  being  recognisable  from  their  skeletons,  the 
family  was  united  by  Agassiz  with  those  of  the  Clupeoids  under 
the  comprehensive  designation  of  Halecidae. 


Genus  SALMO  (Artedi),  Linnaeus. 

[Syst.  Nat.  ed.  10,  1758,  p.  308.] 

Head  large,  and  trunk  elongate-fusiform  with  rounded  abdomen. 
Mouth  deeply  cleft  and  dentition  powerful ;  spaced  conical  teeth  on 
the  ])remaxilla,  maxilla,  dentary,  vomer,  and  palatine,  none  on 
pterygoids.  Paired  fins  of  moderate  size,  the  pelvic  pair  opposed  to 
the  median  dorsal ;  anal  fin  short,  with  not  more  than  14  rays  ; 
caudal  fin  truncate.  Scales  small. 

This  genus  ranges  throughout  the  freshwaters  of  the  arctic  and

temperate  regions  of  the  northern  hemisphere.  It  is  only  definitely 
known  among  fossils  by  unimportant  fragments  of  Pleistocene  age. 
of  which  there  are  none  in  the  Collection. 

The  following  supposed  extinct  species  is  doubtfully  deter¬ 
mined  : — 

Salmoil)  immigratus,  D.  Gr.  Kramberger,  Rad  Jugoslav.  Akad. 
vol.  cvi.  (1891),  p.  102,  pi.  vii.  fig.  4. — Upper  Miocene  ; 
near  Podsused,  Croatia.  [Portion  of  trunk ;  University 
Geological  Museum,  Agram.] 

The  following  supposed  extinct  genus  and  species  is  known  only 
by  the  skull,  which  resembles  that  of  Salmo  but  has  the  maxilla 
subcylindric  or  rod-shaped  instead  of  flat  or  laminar  : —

large  as  Salmo  salar.'] 

The  fish-remains  described  as  follows  are  supposed  to  represent 
another  extinct  genus,  Thaumaturus,  closely  related  to  Salmo,  but 
distinguished  by  the  great  obliquity  of  the  cleft  of  the  mouth  and 
the  crimping  of  the  scales.  There  are  no  examples  in  the  Col¬ 
lection.

Family  HALOSAURID^E. 

Trunk  much  elongated,  the  caudal  region  relatively  large  and 
tapering.  Parietal  bones  in  contact,  excluding  the  supraoccipital 
from  the  cranial  roof ;  squamosals  suturally  united  with  parietals 
and  completely  covering  the  otic  region  ;  snout  a  little  produced ;  a 
suborbital  series  of  enlarged  cheek-plates  bearing  the  well-developed 
slime-canal.  Mandibular  suspensorium  inclined  forwards,  and 
g-ape  of  mouth  small ;  premaxilla  chiefly  forming  the  upper  border 
of  the  mouth,  but  maxilla  also  entering  it ;  teeth  minute  or  rudi¬ 
mentary.  Oj)ereular  apparatus  incomplete,  with  numerous  well¬ 
spaced  slender  branchiostegal  rays,  but  no  gular  plate.  Vertebral 
centra  in  the  form  of  thin  cylinders  jnerced  by  the  notochord ;  ribs 
very  short.  Intermuscular  bones  present.  Fin-fulcra  absent;  fin- 
rays  bifurcated  slightly  and  articulated  at  wide  intervals  in  the 
distal  half ;  pectoral  fins  placed  well  upon  the  flank,,  and  pelvic  fins 
well-developed,  abdominal ;  a  single  dorsal  fin  about  the  middle  of 
the  back ;  anal  fin  much  extended,  sometimes  confluent  with  the 
caudal.  Scales  thin  and  cycloid  ;  lateral  line  conspicuous  along  the

Genus  ECHIDNOCEPHALUS,  W.  von  der  March. 
[Zeitschr.  deutsch.  geol.  Gesell.  vol.  x.  1858,  p.  247.] 

An  imperfectly  known  fish  from  which  the  existing  genus  HaU- 
saurus  is  not  yet  clearly  distinguished.  The  dentition,  cheek-plates, 
and  pectoral  fin  are  unknown,  while  the  number  of  rays  in  the 
dorsal  and  pelvic  fins  is  slightly  less  than  is  usual  in  the  recent 
genus.  Eranchiostegal  rays  about  12  in  number.  Vertebral  centra 
very  short  and  numerous  as  far  as  the  middle  of  the  caudal  region, 
marked  with  delicate  longitudinal  striae.  Dorsal  fin  with  two 
simple,  and  about  six  branched  rays,  arising  behind  the  pelvic  pair 
and  in  advance  of  the  anal,  which  is  much  extended  and  not 
differentiated  from  the  caudal.  Scales  of  lateral  line  thickened  and 
apparently  enlarged.

on  account  of  the  general  resemblance  of  its  skeleton  to  that  of 
Echidnocephalus.  Vertebrae  very  short  and  numerous,  marked  with 
delicate  longitudinal  striae  ;  neural  arches  in  the  abdominal  region 
expanded  into  narrow  laminae.  Paired  fins  small,  about  equal  in 
size ;  dorsal  fin  at  least  as  deep  as  long,  arising  opposite  to  or 
behind  the  pelvic  fins  ;  anal  fin  much  extended  ;  a  separate  fringing

Academy  of  Miinster  some  of  the  anterior  vertebral  centra  seem  to 
show  that  a  large  remnant  of  the  notochord  pierced  them.  The 
haemal  spines  are  somewhat  thickened  but  not  fused  together  at  the 
base  of  the  caudal  fin.  Long  and  delicate  intermuscular  bones  are 
conspicuous,  extending  nearly  to  the  end  of  the  tail.  The  extended 
anal  fin  (“  dorsal”  of  von  der  Marck)  is  clearly  separate  from  the 
caudal,  and  exhibits  remarkably  short  supports.  The  dorsal  fin  is 
represented  only  by  five  articulated  and  divided  rays  opposite  the 
middle  of  the  anal ;  but  the  specimen  is  so  much  distorted  that  the 
original  relationships  of  these  two  fins  are  uncertain. 

Enchelurus  syriaciis,  sp.  nov.

A  species  attaining  a  length  of  about  0T2.  Length  of  head  with 
opercular  apparatus  equalling  twice  the  maximum  depth  of  the 
trunk,  and  probably  contained  about  three  times  in  the  length  from 
the  pectoral  arch  to  the  base  of  the  caudal  fin.  Operculum  nearly 
as  deep  as  broad,  its  hinder  border  slightly  produced  into  a  broad 
crimped  prominence.  Vertebrae  approximately  100  in  number. 
Pelvic  fins,  each  with  about  8  rays,  inserted  opposite  the  origin  of 
the  dorsal  fin,  which  comprises  from  16  to  18  rays,  and  arises  as 
far  from  the  occiput  as  its  termination  from  the  base  of  the  caudal

seems  to  be  a  little  displaced  backwards.  The  cranium  is 
evidently  low  and  elongated,  but  no  other  feature  is 
recognisable  in  the  head.  There  are  remains  of  a 
tolerably  robust  opercular  apparatus,  with  a  few  long 
and  slender  branchiostegal  rays  (hr.)  below.  Part  of 
the  stout  and  broad  clavicle  is  seen,  with  remains  of  the

vacuity  ;  and  fouT  slender  basals  can  be  seen  supporting 
the  appended  pectoral  fin  (pcf.).  The  vertebral  centra  are 
obscure,  but  their  arches  are  distinct ;  the  characteristic 
expansions  of  the  neural  arches  in  the  abdominal  region 
are  especially  well  shown.  The  pelvic  fins  (plv.),  with 
their  closely  apposed  supporting  bones,  are  preserved  just 
in  advance  of  the  dorsal  fin,  which  is  opposed  to  the  space 
between  the  pelvic  pair  and  the  anal.  The  rays  of  the 
dorsal  fin,  probably  about  17  in  number,  are  stouter  than 
those  of  the  anal,  which  seem  to  have  been  shorter  and 
not  less  than  30  in  number.  Of  the  caudal  fin,  only  a

size  in  PI.  XII.  fig.  2.  The  head  is  vertically  crushed 
and  seen  apparently  from  above.  The  postorbital  portion 
of  the  cranium  is  longer  than  broad,  while  the  interorbital 
and  rostral  portions  are  very  slender.  The  left  mandibular 
ramus  is  sufficiently  complete  to  indicate  that  the 
quadrate  articulation  was  beneath  the  hinder  border  of 
the  orbit.  The  operculum  (ojj.)  is  trapezoidal  in  shape, 
and  slightly  crimped  postero-superiorly  ;  an  impression  on 
the  right  suggests  that  the  preoperculum  was  much 
expanded  ;  while  there  are  remains  of  a  suboperculum 
and  very  slender  branchiostegal  rays  on  the  left.  The 
vertebrae  in  the  abdominal  region  bear  the  expanded 
neural  arches,  and  also  short,  slender  ribs.  The  'Column 
is  distorted  just  behind  the  dorsal  fin.  Imperfect  remains 
of  all  the  fins  occur,  including  the  large  and  fringing 
rpointed  caudal  fin.  The  squamation  is  not  well  preserved  ; 
but  one  longitudinal  series  of  scales  near  the  ventral 
border  is  conspicuous,  apparently  by  its  being  thickened, 
not  enlarged.  The  latter  series  doubtless  indicates  the 
course  of  the  lateral  line.  Leivis  Coll.

fig.  3 ;  Lower  Chalk,  probably  Kent.  The  cranium  is 
exposed  from  above,  and  its  roof-bones  are  shown  to  be 
unornamented.  The  postorbital  region  is  at  least  as 
broad  as  long,  while  the  interorbital  and  rostral  regions 
are  much  laterally  compressed.  The  parietal  bones  {;pci.) 
are  large,  meeting  in  the  middle  line  ;  while  the  squa- 
mosals  {sq.)  cover  the  whole  of  the  otic  region,  except 
perhaps  behind.  The  frontals  (/r.)  are  extremely  narrow 
in  their  anterior  half ;  and  the  slender  mesethmoid  {eth.\ 
which  projects  forwards  beneath  them,  exhibits  a  slight 
expansion  at  its  anterior  end.  Among  the  remains  on 
the  side  of  the  cranium,  there  is  a  quadrate  on  the  right, 
and  an  entopterygoid  {enpt.')  on  the  left.  The  quadrate 
bears  a  small  ])Ostero-superior  process,  probably  to  clasp  a 
S3^mplectic.  The  entoj)terygoid  is  a  large  laminar  bone, 
slightly  more  than  twice  as  long  as  deep.  Bemains  of 
the  premaxillee  beneath  the  end  of  the  mesethmoid  indicate 
that  they  must  have  been  relatively  small,  with  a  delicate 
rod-like  extension  behind.  They  distinctly  bear  very 
minute  teeth.  The  maxilla  (mx.),  shown  on  both  sides,  is 
relatively  very  large ;  its  anterior  portion  being  a  stout 
narrow  bar  extending  forwards  above  the  premaxilla, 
while  its  larger  hinder  portion  is  a  considerable  laminar 
expansion,  not  externallj^  ornamented.  The  evidence 
of  teeth  on  this  element  is  uncertain.  The  mandible 
(md.')  seems  to  have  been  comparatively  small,  but  its 
remains  are  imperfect  and  partly  obscured.  There  is, 
however,  reason  to  suspect  that  the  gape  was  small,  and 
that  very  little  of  the  maxilla  entered  it.  The  left 
operculum  (qp.),  though  somewhat  fractured,  shows  its 
oharacteristic  smoothness  and  rounded  posterior  border. 
Fragmentary  remains  of  the  vertebral  axis  are  preserved 
as  far  as  the  pelvic  fins.  The  anterior  vertebral  centra

are  deeper  than  long,  but  those  more  posteriorly  are  about 
as  deep  as  long ;  all  are  marked  by  very  delicate  longi¬ 
tudinal  ridges.  Traces  of  slender  ribs  occur,  and  all  the 
neural  arches  bear  curious  laminar  expansions.  Portions 
of  the  pelvic  fin-supports  {'plv.')  are  distinguishable,  and 
there  are  a  few  indications  of  very  thin  scales.

Notacantlius  and  two  or  three  closely  allied  genera  still  exist  in 
the  deep  sea.  An  account  of  the  osteology  and  anatomy  of  some  of 
the  soft  parts  of  the  type  genus  is  given  by  Gunther \  and  there  is 
some  reason  to  believe  that  the  fish  is  truly  physostomous^. 
Vaillanthas  observed  bone-lacunae  in  several  parts  of  the  skeleton  ^ 

Genus  PRONOTACANTHUS,  novum. 

An  imperfectly  known  genus,  with  laterally-compressed  trunk 
and  an  excessively  elongated  abdominal  region  which  comprises  at 
least  70  vertebrae.  Teeth  recurved,  in  single  regular  series  in  the 
mandible.  A  regular,  spaced  series  of  dorsal  fin-supports  extending 
along  the  whole  length  of  the  abdominal  region,  each  support 
expanded  distally,  but  not  bearing  either  fin-ray  or  spine. 

Pronot acanthus  differs  from  all  the  existing  genera  in  the  absence 
of  dorsal  siDines  or  fin-rays.  It  has  already  been  mentioned  in

numerous  delicate  intermuscular  bones,  so  that  the  non- 
appearance  of  the  characteristic  short  transverse  processes 
is  perhaps  to  be  explained  by  the  imperfections  in  the 
mode  of  preservation.  The  neural  arches  and  spines  are 
very  slender,  and  inclined  sharpl}-  backwards  throughout 
the  length  of  trunk  preserved ;  the  delicate  ribs  seem  to 
have  completely  encircled  the  abdominal  cavity.  Traces 
of  the  contents  of  the  intestine  are  observed  throughout 
the  greater  part  of  the  abdominal  region,  extending  behind 
the  pelvic  fins  nearly  as  far  as  the  specimen  is  preserved. 
One  pectoral  fin  is  bent  upwards  and  the  other  down¬ 
wards,  and  they  are  sufficiently  well  exhibited  to  indicate 
that  they  are  comparatively  large  and  robust,  each  with 
about  10  rays.  The  pelvic  fins  (plv.)  are  very  remote, 
and  observed  to  be  supported  b}’  a  pair  of  slender  bones 
which  are  pointed  in  front.  The  pelvic  fin-rays  are  much 
more  slender  than  those  of  the  pectoral  fins,  and  perhaps 
about  two  thirds  as  long  as  th-e  latter.  The  fish  is  broken 
away  shortly  behind  the  pelvic  fins,  and  neither  side  of 
the  fossil  exhibits  the  additional  fragment  represented  by 
Davis.  Still  further  back  on  the  left-hand  slab,  there 
occurs  the  terminal  portion  of  a  tail  with  a  small  differ¬ 
entiated  caudal  fin ;  but  it  is  very  uncertain  whether  this 
belongs  to  the  fish  now  described.  The  dorsal  fin-supports 
are  well  shown  as  indicated  in  the  drawing,  each  with  a 
small  triangular  expansion  at  its  distal  end ;  but  there 
are  no  traces  of  fin-ravs  in  connection  with  them.  There

cranium  in  side-view  appears  less  deepened  than  in  the

stouter,  its  articulation  below  the  middle  of  the  orbit, 
its  hinder  half  very  much  deepened,  its  short  oral  margin 
still  bearing  three  slender  recurved  teeth.  The  opercular

sively  elongated,  its  vertebral  centra  about  twice  as  long  as  deep, 
and  a  series  of  16  or  17  equalling  the  length  of  the  head;  the  other

P.  4007.  Specimen  figured  by  Davis,  Joe.  cit.  pi.  xxxviii,  fig.  1  ; 

Sahel  Alma.  The  head  is  much  shortened  by  accident, 
the  projecting  premaxillaries  being  broken  away  in  front, 
the  cranium  imperfect  behind  ;  and  the  opercular  region 
is  also  shortened  by  the  distortion  of  the  fish.  The 
cranial  roof  appears  to  be  exposed  from  withiu,  and 
where  the  bone  is  flaked  away  a  small  impression  of  the 
right  frontal  shows  the  longitudinally-ridged  ornament. 
The  characteristic  anterior  termination  of  the  mesethmoid 
is  well-preserved.  The  extent  of  the  very  large  orbit  is 
shown  in  Davis’  flgure;  in  front  there  is  the  usual 
smooth,  ovoid  cheek-plate.  Some  of  the  very  slender, 
backwardly-curved  teeth  are  exhibited  in  remains  of  the 
jaws.  An  impression  of  the  left  operculum  is  seen,  but 
too  imperfect  for  description.  The  vertebrae  can  be 
distinguished  throughout  the  length  of  the  fish  and  seem 
to  have  been  slightly  over  seventy  in  number ;  those 
towards  the  hinder  edge  of  the  abdominal  region  ex¬ 
hibiting  the  robust  transverse  processes,  of  which  each 
bears  a  long  and  very  slender  rib.  The  anterior  half  of 
the  abdominal  region  is  much  distorted,  and  the  pectoral 
fin  is  preserved  on  either  side,  that  of  the  left  side  being 
most  nearly  complete.  Ten  rays  can  be  counted  in  the 
latter,  the  three  foremost  being  much  the  stoutest,  with 
sparse  articulations  in  their  distal  half,  the  others 
comparatively  delicate,  both  articulated  and  subdivided  in 
their  distal  half.  The  pelvic  fins  are  also  squeezed  apart 
and  exhibited  one  on  either  side  of  the  fossil,  arising  about 
twice  as  far  from  the  caudal  as  from  the  pectorals  and 
comprising  a  few  slender  rays  longer  than  those  of  the 
latter.  The  dorsal  and  anal  fins  are  not  preserved,  but 
the  caudal  is  nearly  complete  and  shown  to  be  slightly 
forked,  with  about  six  short  fulcral  rays  at  its  base  above 
and  below.  The  scutes  are  largest  and  shown  partly  in 
double  series  on  the  margins  of  the  fossil,  and  thev 
distinctly  form  a  continuous  line  along  the  regions  which 
would  be  occupied  by  the  dorsal  and  anal  fins.  They  are 
all  triradiate,  with  slender  branches,,  and  longitudinally

ridged  but  apparently  unornamented.  On  the  ventral 
border  of  the  caudal  region  each  scute  bears  a  well- 
developed,  posteriorly-directed  uncinate  spine  ;  and  nearly 
the  whole  series  here  is  exposed  in  side  view.  Scutes  of 
this  kind  are  similarly  observed  in  the  fragmentary  type 
specimen  described  by  Pictet.  The  scutes  of  the  flanks 
are  smaller  and  more  delicate,  but  not  clearly  shown. 
Near  the  dorsal  border  of  the  anterior  abdominal  region 
some  of  these  occur  in  a  regular  series,  apparently  pierced 
by  the  slime- canal  of  the  lateral  line,  and  having  the 
anteriorly-directed  pierced  ray  very  large  in  comparison 
with  the  others.  Somewhat  larger  scutes  of  the  same 
form  appear  again  in  series  below  the  vertebral  column  in 
the  neighbourhood  of  the  pelvic  fins  ;  and  others  seem  to 
be  crushed  upon  the  transverse  processes  of  the  vertebrae  in 
the  same  region.  Eemains  of  lath-shaped  plates  on  the 
flank  are  also  distinguishable  on  the  anterior  half  of  the 
caudal  region.  Lewis  Coll. 

49536.  A  larger  fish,  wanting  the  greater  part  of  the  head  but 
displaying  the  dorsal  fin,  noticed  by  Davis,  loc.  cit.  p.  620 ; 
Sahel  Alma.  About  70  vertebrae  can  be  distinguished, 
and  those  in  the  hinder  part  of  the  abdominal  region 
exhibit  the  usual  very  large  transverse  processes,  from  the 
extremities  of  which  very  slender  and  nearly  straight  ribs 
are  suspended.  The  remains  of  the  paired  fins  are  too 
fragmentary  for  description  ;  but  the  pelvic  pair  seems  to 
be  in  its  natural  position,  arising  just  behind  a  point 
opposite  the  origin  of  the  dorsal,  and  its  rays  are  shown 
to  be  finely  divided  distall}^  The  dorsal  fin  occupies 
nearly  the  middle  third  of  the  back,  ihe  distance  between 
its  origin  and  the  occiput  about  equalling  that  between 
its  termination  and  the  caudal  fin.  All  its  rays  are 
simple  in  the  proximal  half,  but  articulated  at  wide 
intervals  and  subdivided  in  the  distal  half.  The  foremost 
two  or  three  rays  are  shown  only  in  impression,  but  the 
others  are  well-preserved,  and  the  total  number  seems  to 
have  been  about  thirty-five.  About  twelve  of  the  hinder- 
most  rays  are  much  more  delicate  and  shorter  than  the 
others.  The  anal  fin  is  wanting,  but  the  caudal  fin  is 
preserved,  showing  the  cluster  of  basal  scales  above  and 
the  distant  articulations  of  its  rays.  The  dorsal  and 
ventral  marginal  scutes  are  preserved,  but  nearly  all  are

Science,’  vol.  xii.  (1898),  p.  258,  pi.  x. ;  Sahel  Alma. 
The  specimen  is  interesting  as  enclosing  an  undigested 
fish  O’OTo  in  length,  which  has  been  swallowed  as  usual 
head  foremost,  and  distends  the  hinder  abdominal  region 
from  a  depth  of  less  than  0'015  to  more  than  0‘02. 
Among  the  fractured  remains  of  the  head  the  character¬ 
istic  end  of  the  rostral  region  is  distinct,  ornamented  by 
a  few  smooth  longitudinal  ridges.  Behind  the  head  the 
pectoral  fin  is  shown  fragmentarily  on  each  side.  jS^ine 
rays  seem  to  be  indicated  on  the  right  side,  those  beyond 
the  foremost  four  being  comparatively  delicate  and  short, 
but  all  with  widely-spaced  articulations  at  the  distal  end 
and  the  majority  bifurcated.  The  foremost  ray  on  the 
left  side,  also  showing  distal  articulations,  measures  0’02 
in  length.  The  number  of  vertebrae  exhibited  seems  to 
be  about  80.  The  pelvic  fins,  represented  by  that  of  the 
left  side  displaced  downwards  b}’  the  distended  stomach, 
are  as  large  as  the  pectorals,  and  nearly  similar,  but 
apparently  with  stouter  rays  which  are  only  six  in 
number.  The  pelvic  fin-support  is  a  delicate  expanded 
lamina,  not  clearly  seen.  The  anal  fin  is  well-preserved, 
about  twice  as  deep  as  long,  comprising  seven  or  eight 
stout,  closelv-arranged  ravs,  each  undivided  in  the 
proximal  half,  bifurcated  and  with  distant  articulations 
in  the  distal  half.  The  distance  between  this  fin  and  the 
pelvic  pair  (displaced)  is  somewhat  less  than  that  between 
the  latter  and  the  pectorals,  and  not  quite  twice  as  great 
as  that  between  its  origin  and  the  caudal.  The  dorsal  fin 
is  wanting.  The  caudal  is  a  little  crushed,  but  exhibits 
the  characteristic  bifurcation.  The  triradiate  dorsal  and 
ventral  scutes  are  shown  along  the  entire  length  of  the 
trunk  as  far  forwards  as  the  pectoral  arch,  except  above 
the  distended  stomach  and  the  base  of  the  anal  fin  ;  aU

those  ill  advance  of  the  pelvic  fins  being  conoparatively 
slender.  Most  of  those  in  the  caudal  region  are  exposed 
from  the  inner  aspect,  and  the  uncinate  spine  is  thus 
only  visible  on  a  few  dorsal  scutes  of  the  caudal  pedicle. 
There  are  traces  of  scutes  on  the  flanks,  but  they  are  not 
distinct.  Lewis  Coll. 

49541.  Equally  large  fish,  the  head  and  anterior  abdominal  region 
exposed  from  below,  the  remainder  of  the  trunk  from  the 
side  ;  Sahel  A^ma.  The  imperfect  long  and  slender  man¬ 
dible  is  shown  from  below,  the  ramus  of  the  right  side  with 
five  large  pits  in  sparse  longitudinal  series  at  its  anterior 
end.  A  fracture  seems  to  indicate  the  division  between 
the  dentary  and  articulo-augular  elements  ;  if  so,  the 
latter  is  almost  as  long  as  the  former.  Traces  of  very 
slender  branchiostegal  rays  are  observed  behind,  seven 
being  indicated  on  the  right,  and  possibly  more  on  the 
left  side.  Slightly  more  than  seventy  vertebrse  can  be 
counted,  and  some  of  the  characteristic  centra  in  the 
anterior  abdominal  region  exhibit  the  laminar  transverse 
processes.  The  pectoral  fins  are  imperfectly  preserved  on 
each  side  of  the  trunk,  and  that  of  the  right  distinctly 
indicates  eleven  rays,  the  hindermost  excessively  delicate. 
The  pelvic  fins  are  shown  only  in  a  fragment  opposite 
the  anterior  end  of  the  dorsal  fin,  of  which  the  foremost 
nine  or  ten  rays  are  preserved.  The  anal  fin  is  almost 
destroyed,  but  the  caudal  fin  is  not  much  injured.  The 
marginal  scutes  are  of  the  usual  form  and  proportions, 
distinctly  in  continuous  series  along  the  base  of  the  dorsal 
and  anal  fins;  some  on  the  ventral  border  of  the  mid- 
caudal  region  are  exposed  in  side-view  and  display  the 
relatively  large  uncinate  spine,  which  becomes  greatly 
reduced  on  the  corresponding  scutes  of  the  caudal  pedicle. 
The  appearances  on  the  flank  are  difiicult  of  interpreta¬ 
tion;  but  below  the  vertebral  column  just  behind  the 
pectoral  fins  there  is  a  series  of  narrow  heart-shaped 
scutes  shown  from  the  inner  face,  which  seem  to  have 
borne  a  median  longitudinal  keel ;  and  below  these  again, 
especially  a  little  further  hack,  there  are  traces  of  the 
oblique  lath-shaped  plates,  which  are  still  better  observed 
on  the  caudal  region.  At  the  base  of  the  anal  fin, 
indeed,  three  of  these  lath-shaped  plates  seem  to  be 
directly  continuous  with  the  postero-superiorly  inclined

49537.  Imperfect  contorted  fish,  with  reflexed  head ;  Sahel  Alma. 

Immediately  in  front  and  behind  the  orbit  there  aro 
remains  of  a  delicate  plate,  which  may  belong  to  the 
cheek.  Clustered  slender  conical  teeth  are  observed  in 
the  jaws.  Some  of  the  anterior  vertebrae  exhibit  the 
characteristic  laminar  transverse  processes,  while  a  few  of 
the  caudals  still  bear  the  short  neural  spine.  The  large 
pelvic,  fins  are  crushed  together  in  the  usual  situation. 
The  dorsal  fin  is  evidentlv  similar  to  that  of  no.  TObSG, 
but  the  rays  are  depressed  and  cannot  be  counted ;  some 
of  its  supports  are  distinct  in  the  hinder  part,  each  much 
expanded  at  the  articulation  with  the  corresponding  ray. 
Immediately  before  and  behind  the  dorsal  fin  the  double 
series  of  dorsal  scutes  is  preserved,  those  of  both  sides 
being  exposed  from  the  inner  aspect ;  it  is  also  clear  that 
this  double  series  was  continuous  along  the  base  of  the 
fin.  A  few  of  the  ventral  scutes  are  shown  from  the 
external  aspect,  with  spine  broken  away,  in  the  hinder 
part  of  the  caudal  region ;  and  those  of  the  left  side  are 
exposed  in  continuous  series  above  the  base  of  the  anal  fin. 
The  caudal  fin  is  expanded  by  crushing.  Leivis  Coll.

be  distinguished  some  of  the  narrow  heart-shaped  flank- 
scutes,  becoming  more  markedly  triradiate  near  the  origin 
of  the  dorsal  fin  ;  while  between  this  row  and  those  on

of  the  articulo-angular  element  of  the  mandible  is 
distinct,  while  a  few  of  the  slender  branchiostegal  rays 
occur  below.  The  clavicle  is  shown  to  be  robust,  and  the 
pelvic  fin-support  expanded.  Remains  of  an  undigested 
individual,  apparently  of  Leptotraclielus  gracilis,  extend 
along  the  whole  length  of  the  abdominal  region  ;  and 
there  are  some  rounded  bodies  clustered  in  advance  of 
the  pelvic  fins,  which  may  be  ova.  Lewis  Coll.

counterpart ;  Sahel  Alma.  The  rostral  region  and  an 
impression  of  the  remainder  of  the  cranial  roof  exhibit  an 
ornamentation  of  delicate  raised  lines  and  rows  of  small 
tubercles ;  those  on  the  mesethmoid  in  a  longitudinal 
direction,  those  on  the  hinder  part  of  the  frontal  more  or 
less  radiating  and  scarcely  reaching  its  posterior  border. 
The  mandibular  ramus  of  the  left  side  is  shown  to  be 
similarly  ornamented  with  longitudinal  series  of  fine 
tubercles.  The  slender  teeth  are  clustered  as  usual. 
Remains  of  the  slender  spaced  branchiostegal  rays  are 
seen,  about  12  on  the  left  side.  The  right  pectoral  fin 
exhibits  11  rays,  all  distantly  articulated  at  the  distal 
end,  and  all  except  the  first  two  bifurcating  twice  distally. 
The  anterior  vertebral  centra  are  not  more  than  twice  as 
long  as  deep.  Egerton  Ennishillen  Colls.

fin.  Anterior  abdominal  region  excessively  slender,  and  its  vertebral 
centra  about  three  times  as  long  as  deep,  with  much  expanded 
transverse  processes  ;  a  series  of  13  or  14  anterior  vertebrae  equalling 
the  length  of  the  head ;  the  other  vertebral  centra  a  little  deeper 
in  proportion  to  their  length.  Pelvic  fins  much  larger  than  the 
pectorals,  arising  just  in  advance  of  the  middle  point  of  the  trunk, 
the  distance  between  the  pectoral  and  pelvic  pairs  equalling  twice 
the  length  of  the  head  with  opercular  apparatus  ;  dorsal  fin  occup\lng 
less  than  the  middle  third  of  the  trunk  ;  number  of  fin-rays  probably 
as  in  Z.  triqueter.  Dermal  scutes  narrow,  those  on  the  dorsal  and 
ventral  border  of  the  elongated  abdominal  region  excessively 
attenuated  ;  anterior  abdominal  fiank-scutes  narrow  heart-shaped. 

It  seems  probable  that  the  fragments  named  Deixetis  tenuis  by 
Pictet  (Poiss.  Foss.  Mont  Liban,  1850,  p.  46,  pi.  ix.  figs.  1-4) 
belong  to  this  species ;  but  they  are  too  imperfect  for  certain 
determination.

48086.  Type  specimen  figured  by  Davis,  loc.  cit.  ;  Sahel  Alma. 

The  end  of  the  snout  is  broken  away,  and  the  flaking  of 
the  bone  exposes  some  of  the  slender  clustered  teeth  of 
the  upper  jaw.  The  delicate  ovoid  plate  at  the  anterior 
border  of  the  orbit  is  distinct ;  and  a  curved  plate  much 
broader  than  deep,  just  in  front  of  the  clavicle,  may  be 
the  suboperculum.  The  very  slender  vertebrae  of  the 
somewhat  distorted  abdominal  region  exhibit  the  ex¬ 
panded  transverse  processes  ;  and  the  characteristic  dermal 
scutes  are  distinct  as  far  forwards  the  pectoral  fin. 
The  total  number  of  vertebrae  seems  to  be  between  70 
and  80.  The  scntes  on  the  ventral  border  become  notably 
enlarged  towards  the  base  of  the  pelvic  fins,  which  seem 
to  have  been  larger  than  the  pectorals.  The  long  trans¬ 
verse  processes  of  the  vertebras  are  well  shown  in  the 
region  between  the  remains  of  the  dorsal  and  pelvic  fins. 
Further  back  one  of  the  ventral  caudal  scutes  is  exposed 
in  side  view,  dis])laying  a  small  uncinate  spine  and  one 
arm  distinctly  produced  into  one  of  the  lath-shaped  plates, 
which  are  very  conspicuous.  The  anal  fin  is  represented 
only  by  five  fragmentary  rays.  The  caudal  fin  is  similar 
to  that  of  L.  triqueter.  Leiuis  Coll.

transverse  processes  of  the  vertebrae  in  the  hinder 
abdominal  region  are  shown  in  impression  ;  the  expanded 
pelvic  fin-supports  are  also  preserved.  The  very  narrow 
ventral  scutes  of  the  anterior  abdominal  region  are  shown 
to  pass  rapidly  into  much  larger  scutes  with  widely- 
spreading  lateral  branches  towards  the  base  of  the  pelvic 
fins,  and  these  continue  for  some  distance  beyond.  Some 
of  the  marginal  scutes  of  the  hinder  caudal  region  are 
very  clearly  produced  into  the  lath-shaped  plates  of  the 
flank.  Lewis  Coll.

P.  4852.  Imperfect  anterior  portion  of  fish,  noticed  and  the  head 
figured  by  Davis  (Trans.  Hoy.  Dublin  Soc.  [2]  vol.  iii. 
1887,  p.  622,  pi.  xxxviii.  fig.  2)  under  the  name  of 
Leptotraclielus  triquetei\  var.  a\  Sahel  Alma.  The  head 
is  shown  in  lateral  aspect,  much  fractured,  with  some  of 
the  slender  clustered  teeth  exposed ;  while  fragments 
of  the  external  bones  in  the  hinder  portion  of  the 
cranial  roof  and  in  the  mandible  are  ornamented  with 
very  fine  tubercles.  These  tubercles  on  the  dentary  and 
angular  bones  are  arranged  in  obliquely-directed,  nearly 
parallel  lines.  The  opercular  apparatus  is  evidentH 
well-developed,  though  the  separate  elements  cannot  be 
distinguished.  The  vertebral  centra  are  similar  in  pro¬ 
portions  to  those  of  L.  gracilis,  and  show  some  of  the 
expanded  transverse  processes  supporting  remarkably 
slender  ribs.  Above  the  vertebral  column  there  are 
longitudinally  extended  rods  stouter  than  the  ribs,  which 
seem  to  be  intermuscular  bones.  Above  the  vertebrae  at 
the  hinder  end  of  the  fossil  may  also  be  observed  the 
narrow  heart-shaped  scutes  of  the  flank,  which  are 
ornamented  with  radiating  lines  of  flne  tubercles.  The 
dorsal  and  ventral  borders,  with  their  scutes,  are  broken

much  attenuated  rostrum.  Anterior  abdominal  region  short,  and 
vertebral  centra  not  more  than  twice  as  long  as  deep  ;  total  number 
of  vertebrae  probably  about  60.  Length  of  head  with  opercular 
apparatus  about  equalling  the  distance  between  the  pectoral  and 
pelvic  fins ;  distance  between  the  pelvic  and  anal  fins  considerably 
greater.  Dorsal  and  ventral  triradiate  scutes  much  attenuated.

quarter  of  the  cranial  length  ;  the  length  of  the  head  with  opercular 
apparatus  contained  between  four  and  five  times  in  the  total  length 
of  the  fish  to  the  base  of  the  caudal  fin.  Anterior  abdominal 
vertebral  centra  about  three  times  as  long  as  deep,  those  beyond 
less  elongated,  and  those  in  the  hinder  half  of  the  abdominal  region 
with  large  transverse  processes.  Pelvic  fins  in  advance  of  the 
middle  of  the  trunk ;  [other  fins  unknown].  Dermal  scutes  of 
moderate  size  and  narrow,  more  or  less  ornamented  with  short 
ridges  and  spinous  tubercles,  those  on  the  dorsal  and  ventral 
borders  of  the  caudal  region  also  bearing  a  slender  backwardly- 
directed  uncinate  spine. 

To  this  species  Agassiz  originally  referred  the  specimens  from  the 
Chalk  of  Lewes  described  and  figured  as  Murcena  ?  lewesiensu  by 
G.  A.  Mantell,  Loss.  South  Downs  (1822),  p.  232,  pi.  xxxiv.  fig.  11, 
pi.  xl.  fig.  2.  These  fossils  subsequently  proved  to  be  merely  worm- 
burrows  lined  with  various  scales  of  fishes  (W.  Davies,  Geol.  Hag. 
[2]  vol.  vi.  1879,  p.  145) ;  and  similar  specimens  from  the  Turonian 
of  Bohemia  were  described  under  the  name  of  Lepidenteron  longis- 
simum  (A.  Pritsch,  Eept.  u.  Pische  bohm.  Xreideform.  1878,  p.  19,

49793.  Head  and  anterior  part  of  trunk,  in  counterpart,  the  cranial 
roof  shown  of  the  natural  size  in  PI.  XII.  figs.  4,  4  u  ; 
Lewes.  This  cranial  roof  is  fiaked  in  such  a  way  that 
some  pieces  remain  on  one  side  of  the  fossil  (fig.  4),  and  the 
rest  on  the  counterpart  (fig.  4  a).  The  postorbital  region 
of  the  skull  occujues  one  quarter  of  its  total  length,  and  is 
about  as  long  as  broad,  wuth  parallel  sides  and  the 
occipital  border  excavated  by  a  sharp  re-entering  angle. 
The  frontal  region  between  the  orbits  is  excessively 
constricted  in  front.  All  the  external  bones  are 
ornamented  with  a  few  delicate  longitudinal  ridges, 
occasionally  subdivided  into  tubercles.  When  the  roofing 
bones  are  removed,  as  in  fig.  4,  the  well-ossified  though 
small  supraoccipital  can  be  observed  beneath,  bearing  a 
slight  vertical  median  crest ;  but,  as  shown  by  the 


186 


ACTINOPTEBYGII. 


impression  of  the  external  aspect  of  the  roof  on  the  other 
side  of  the  fossil,  this  bone  is  not  exposed  above.  The 
parietals  (p«.)  are  an  unsymmetrical  pair  of  plates, 
broader  than  long,  meeting  throughout  their  length  in 
a  slightly  sigmoidal  suture,  and  marked  by  about  two 
ridges  which  extend  from  border  to  border,  w^hile  other 
short  ridges  and  tubercles  are  observed  behind.  The 
squamosals  (sq.)  seem  to  have  been  very  narrow  and 
insignificant  plates  at  the  postero-lateral  angles  of  the 
skull,  not  extending  further  forwards  than  the  parietals. 
The  frontals  (fr.)  extend  and  expand  backwards  to  form 
more  than  half  the  postorbital  region  of  the  cranial  roof  ; 
and  these  are  not  a  symmetrical  pair,  that  of  the  right 
side  being  wider  and  extending  further  backwards  than 
that  of  the  left  side.  The  few  ornamental  ridges  on  these 
bones  do  not  quite  reach  the  hinder  margin  and  are  in  no 
way  connected  or  correlated  with  those  on  the  parietals. 
The  very  narrow  interorbital  region  is  comj)aratively 
stout,  and  impressions  suggest  that  a  delicate  crescent- 
shaped  wing  extended  upwards  and  outwards  from  the 
frontal  on  each  side  to  protect  the  relatively  large  eye¬ 
ball.  The  anterior  end  of  the  frontals  seems  to  have 
expanded  a  little  again  on  the  rostral  region,  two  wings 
of  membrane-bone  being  crushed  iu  the  fossil  on  the  sides 
of  the  ethmoid  and  these  are  apparently  directly  con¬ 
tinuous  with  the  frontals.  The  orbit  (orb.)  occupies  one 
quarter  of  the  length  of  the  skull,  and  at  its  anterior 
border  on  each  side  there  is  a  thin,  ovoid,  convex  plate, 
which  seems  to  be  a  dermal  or  membrane-bone.  The 
well-ossified  mesethmoid  (eth.)  is  marked  by  numerous 
fine  longitudinal  ridges  terminating  a  little  behind  the 
anterior  end,  which  is  scarcely  expanded  but  is  curiously 
truncated  and  hollowed  in  front  in  such  a  way  as  to  give 
it  the  appearance  of  being  a  tube.  The  crushed  jaw¬ 
bones  lie  on  either  side  of  the  rostral  region,  and  extend 
for  a  short  distance  in  advance  of  it,  tapering  to  an  acute 
point.  The  bases  of  a  single  regular  close  series  of  minute 
teeth  in  the  dentary  are  observable  on  the  left  side.  Im¬ 
mediately  behind  the  occiput,  and  pointing  to  its  median 
re-entering  angle,  the  pair  of  post-temporal  plates  (p.t.) 
is  preserved ;  each  being  triangular  in  shape,  longer  than 
broad,  and  unornamented  on  its  outer  face.  Just  behind 
these  again  is  one  of  the  narrow  heart-shaped  scutes,

Family  ENCHODONTFDiE. 

Supraoccipital  bone  not  prominent,  but  extending  forwards  to 
the  frontals  and  separating  the  small  parietals  in  the  median  line  ; 
squamosal  reduced,  only  partly  covering  the  otic  region,  which 
projects  laterally  ;  no  basicranial  canal ;  snout  not  produced  ;  cheek- 
plates  well  developed.  Mandibular  suspensorium  vertical  or 
inclined  backwards,  and  gape  of  mouth  wide  ;  premaxilla  delicate, 
considerably  extended  and  excluding  a  great  part  of  the  slender 
maxilla  from  the  upper  border  of  the  mouth  ;  teeth  fused  with  the 
supporting  bone,  not  in  complete  sockets,  those  on  the  pterygo¬ 
palatine  arcade  and  dentary  the  largest.  Opercular  apparatus 
complete,  with  few  slender  branchiostegal  rays  and  no  gular  plate. 
Vertebral  centra  well  ossified,  none  with  transverse  processes ;  ribs 
not  completely  encircling  the  abdominal  cavity ;  a  compound 
hypural  bone  at  the  base  of  the  tail.  Intermuscular  bones  present. 
Fin-fulcra  absent ;  the  rayed  dorsal  fin  never  much  extended, 
usually  near  the  middle  of  the  back,  and  sometimes  an  adipose  fin 
behind.  Scales  delicate  or  absent ;  but  occasional  longitudinal 
series  of  scutes,  the  dorsal  series,  when  present,  being  unpaired. 

The  nearest  living  allies  of  this  extinct  family  appear  to  be  the 
Odontostomidse  and  Alepisauridse,  in  both  of  which  the  margin  of 
the  upper  jaw  is  formed  exclusively  by  the  premaxilla,  while  in  the 
first  the  large  teeth  are  depressible.  Only  three  genera  are  known, 
Odontostowus^  Omosudis,  and  Alepisaurus  {Flagyodus),  all  from  the 
deep  sea.  ,  ^

slender  teeth,  gradually  diminishing  in  size  backwards  ;  no  teeth 
barbed.  Operculum  strengthened  on  the  inner  side  by  a  ridge 
extending  horizontally  backwards  from  the  point  of  suspension  ; 
branchiostegal  rays  about  12  to  1(3  in  number.  Vertebrae  40  to  50 
in  number,  about  half  being  caudal ;  he  centra  at  least  as  long  as 
deep,  constricted  mesially,  and  marked  with  small  irregular  longi¬ 
tudinal  ridges.  All  except  the  foremost  rays  of  each  fin  finely 
divided  distally,  but  none  excessively  elongated.  Xo  postclavicular 
plate.  Pectoral  fins  large,  pelvic  fins  much  smaller  and  arising  far 
forwards  ;  dorsal  and  anal  fins  large,  neither  much  longer  than 
deep,  the  former  arising  much  in  advance  of  the  middle  point  of 
the  trunk,  the  latter  also  far  forwards  ;  [a  posterior  adipose  dorsal 
fill  observed  in  a  few  well-preserved  specimens ;]  caudal  fin  forked, 
with  curved  fulcral  rays  and  stout,  articulated,  undivided  rays  at 
its  base  both  above  and  below.  Rudimentary  dermal  scutes,  nob 
overlapping,  in  a  single  median  series  between  the  occiput  and  the 
dorsal  fin,  and  along  the  course  of  the  lateral  line  ;  a  pair  of 
enlarged  hook-shaped  dermal  scutes  at  the  base  of  the  tail,  one  on 
either  side  of  the  caudal  pedicle.

small,  but  the  mandible  sometimes  attaining  a  length  of  0*1.  The 
sides  of  the  cranial  roof  and  the  outer  face  of  the  mandible 
ornamented  with  numerous  and  closely-arranged  sharp  ridges,

mostly  radiating  and  each  bearing  a  series  of  small  tubercles  ;  these 
ridges  on  the  dentary  bone  radiating  from  the  symphysis,  on  the 
articulo-angular  bone  radiating  from  the  mandibular  articulation. 
Palatine  bone  produced  forwards  as  a  short  cylindrical  extension  in 
advance  of  the  ethmoid  articulation,  and  the  long  slender  tooth, 
antero-posteriorly  compressed,  fixed  at  its  extremity  at  right-angles 
to  the  long  axis  of  the  bone  ;  the  outer  face  of  the  premaxilla  only 
sparsely  ridged  ;  dentary  rapidly  contracting  almost  to  a  point  at 
the  symj)hysis,  where  it  exhibits  about  three  large  irregular 
processes;  the  mandibular  ramus  considerably  deepened  behind,  its 
maximum  depth  nearly  equalling  one  third  of  its  total  length  ; 
about  six  large  mandibular  teeth,  all  both  slender  and  little  curved. 
Teeth  much  compressed,  and  some  delicately  striated,  none  con¬ 
spicuously  serrated  on  the  edges.  Operculum  nearly  two  thirds  as 
broad  as  deep,  marked  by  numerous  sharp,  radiating,  tuberculated 
ridges.

of  the  cranium  is  shown  above  the  orbit  and  otic  region, 
and  exhibits  the  usual  ornament  of  tubercles  on  ridges. 
A  fragment  of  the  parasphenoid,  the  left  hyomandibular 
(Jim.'),  and  left  metapterygoid,  are  exposed,  but  too 
imperfect  for  description.  The  fractured  remains  of  the 
left  premaxilla  with  its  characteristic  ornament, 

obscure  the  pain  tine  and  part  of  the  ectopterygoid  {ecpt.)^ 
but  most  of  the  teeth  of  these  inner  elements  are  shown. 
The  palatine  tooth  {pal.)  is  much  the  largest  and  exhibits 
very  feeble  traces  of  longitudinal  striation.  The  left 
mandibular  ramus  is  well-displayed,  though  imperfect 
anteriorly  and  a  little  fractured  behind.  The  upper  part 
of  the  dentary  {d.)  is  flattened  on  the  outer  face  and 
ornamented  by  tubercles  with  no  definite  arrangement, 
while  in  its  lower  portion  a  few  tuberculated  ridges 
radiate  from  the  symphysis  backwards  and  downwards ; 
The  precise  boundary  of  the  articulo-angular  {ag.),  which 
'is  similarly  ornamented,  is  not  clear.  The  mandibular 
teeth  are  straight  and  more  slender  than  those  of  the 
palato-pterygoid  arcade.  The  deep  and  narrow  tuber- 
'culated  preoperculum  (p.op.)  is  partly  shown,  and  there 
are  traces  of  a  small  reflection  at  its  lower  end  which  may 
have  been  a  short  spine.  The  operculum  (op.),  exhibiting 
'numerous  radiating  lines  of  small  tubercles,  is  for  the 
most  part  beautifully  preserved  ;  and  the  equally  ornate 
suboperculum  (s.oj?.),  with  rows  of  tubercles  chiefly 
directed  downwards,  is  also  represented  by  a  large 
fragment.  Egerton  Coll.

Maastricht.  The  cranium  is  somewhat  obscured  and 
fractured,  but  the  general  characters  of  the  cranial  roof 
(PI.  XI.  fig.  6)  can  be  observed.  The  plane  of  the  occiput 
is  about  at  right-angles  to  that  of  the  roof,  and  the 
occipital  border  exhibits  the  five  prominences  characteristic 
of  the  higher  fishes.  The  small  median  eminence,  partly 
broken  away,  is  formed  by  the  supraoccipital  bone  (s.occ.), 
which  seems  to  enter  the  cranial  roof  as  a  short  and  broad 
plate.  The  inner  pair  of  prominences  are  formed  by  the 
large  and  robust  epiotics  {ep.o.) ;  the  outer,  or  pterotic, 
prominences  {pt.o.)  are  broken,  but  the  right  side  of  the 
fossil  exhibits  a  delicate  plate  of  bone  extending  forwards 
and  inwards  presumably  upon  the  pterotic  element  to  the 
ridge  on  the  frontal  at  the  level  of  the  hinder  border 
of  the  orbit.  The  outlines  of  the  parietal  bones  are 
not  shown,  and  the  precise  limits  of  the  hinder  end  of 
the  frontals  are  uncertain.  The  frontals  (/r.),  however, 
extend  remarkabl)-  far  backwards,  and  are  evidently 
ridged  in  the  manner  characteristic  of  the  genus,  though 
the  inwardly  directed  triangular  ridged  area  spreading 
backwards  along  the  postorbital  region  is  broken  away. 
The  ridges  are  all  sharp,  but  not  tubereulated,  and  the 
smooth  median  area  occupies  nearly  the  inner  half  of  the 
bone.  The  elements  of  the  palato-pterygoid  arcade  are 
almost  completely  covered  by  matrix  and  the  investing 
bones,  though  some  of  the  teeth  are  partly  seen.  The 
delicate  laminar  premaxilla  (fig.  pmx.')  is  imperfectl}" 
shown  on  both  sides,  and  that  of  the  right  is  fractured  by 
being  crushed  on  one  of  the  ectopterygoid  teeth  (x.)  ; 
it  is  a  deepened  plate  of  bone  in  its  anterior  half,  tapering 
to  a  very  slender  production  behind,  and  must  have 
formed  the  margin  of  at  least  half  the  gape.  It  bears  a 
regular  close  series  of  very  small  teeth  on  its  oral  border, 
these  being  indicated  by  their  bases  on  the  left,  by  a  few 
crowns  on  the  right  side.  The  very  slender  maxilla  (ma*.), 
best  shown  by  a  fragment  on  the  right  side,  bears  still 
smaller  closely-set  teeth.  In  its  crushed  state  the  region 
of  the  cheek  on  the  left  side  is  covered  in  front  by  two 
bones  which  cannot  be  satisfactorily  determined.  The 
foremost  exhibits  an  external  ornament  of  radiating  lines 
of  very  fine  tubercles,  and  may  possibly  belong  to  the 
opercular  apparatus.  The  other  is  deep  and  narrow,  with 
,a  triangular  exiiansion  below,  exposed  from  the  inner

aspect,  and  perhaps  representing  the  left  clavicle.  The 
mandible  is  fractured,  and  the  ar'ticulo-angular  element  a 
little  displaced  with  respect  to  the  dentaiy.  Both  these 
bones  are  smooth,  marked  only  by  a  few  grooves  and 
ridges.  On  the  dentary  (d.)  one  groove  extends  directly 
backwards  from  the  symphysis  just  below  the  oral  border, 
widening  on  the  upper  hinder  extension  of  the  bone, 
which  seems  to  reach  the  articular  end  of  the  mandible ; 
while  a  band  of  about  six  similar  grooves  extends  back¬ 
wards  and  a  little  downwards  from  a  point  near  the 
symphysis  to  the  short  lower  hinder  extension  of  the  bone. 
On'  the  articulo-angular  {ag.}  the  grooves  radiate  from 
the  postero-inferior  angle,  one  set  continuing  the  lower 
band  on  the  dentary  already  mentioned.  Some  of  the 
characteristic  large  teeth  are  preserved,  and  the  outer 
border  of  the  dentary  is  shown  to  bear  a  close  regular 
series  of  small  slender  teeth.  Behind  the  skull  are 
remains  of  the  right  operculum  bent  inwards,  this  being 
ornamented  with  very  delicate  tubercles  and  radiating 
lines.  Between  the  mandibular  rami  are  observed  traces 
of  the  hyoid  apparatus  and  branchiostegal  rays  too  im¬ 
perfect  for  description.  Numerous  vertebral  centra,  in 
various  states  of  preservation,  are  clustered  round  the 
head.  They  are  longer  than  deep,  much  constricted,  and 
strengthened  with  delicate  longitudinal  ridges  at  the  side. 
A  triangular  hypural  bone  is  also  preserved.

Type.  Distorted  small  fish ;  Geneva  Museum. 

A  small  species  known  by  nearly  complete  fishes  attaining  a 
length  of  about  OB.  Length  of  head  whth  opercular  apparatus 
much  exceeding  the  maximum  depth  of  the  trunk  and  occupying 
one  third  of  the  total  length  to  the  base  of  the  caudal  fin.  The 
mandible,  operculum,  and  most  of  the  other  external  bones  orna¬ 
mented  with  fine  tuberculated  ridges.  Palatine  bone  produced 
forwards  as  a  short  cylindrical  extension  in  advance  of  the  ethmoid 
articulation,  and  the  long  slender  tooth  fixed  at  its  extremity  ; 
outer  face  of  premaxilla  apparently  smooth ;  dentary  rapidly  con¬ 
tracting  almost  to  a  point  at  the  symphysis,  and  the  maximum 
depth  of  the  mandibular  ramus  contained  about  three  and  a  half  or 
four  times  in  its  total  length.  Teeth  slender,  much  compressed, 
and  often  delicately  striated.  Vertebrge  about  40  in  number,  24 
being  caudal.  Pelvic  fins  somewhat  smaller  than  the  pectorals, 
arising  opposite  the  anterior  half  of  the  dorsal ;  dorsal  fin  with  16 
rays,  its  depth  about  equalling  that  of  the  trunk  at  its  insertion  ;  anal 
fin  much  smaller,  with  18  rays,  arising  nearer  to  the  pelvic  fins  than 
to  the  caudal.  Dorsal  scutes  three  or  four  in  number,  broadly  oval, 
and  ornamented  with  delicate  radiating  lines.

mented  with  fine  tuberculated  ridges.  Maximum  depth  of  man¬ 
dibular  ramus  contained  about  four  times  in  its  total  length. 
Vertebrae  about  50  in  number.  Pectoral  fins  with  14  or  15  rays ; 
pelvic  fins  much  smaller,  with  at  least  6  rays,  arising  opposite  the 
origin  of  the  dorsal;  dorsal  fin  with  18  rays,  of  which  the  three 
foremost  are  gradually  lengthening  spines;  anal  fin  arising  much 
nearer  to  the  pelvic  fins  than  to*  the  caudal  and  comprising  25  rays, 
of  which  the  three  foremost  are  gradually  lengthening  spines. 
Dorsal  scutes  four  in  number,  elongate-rhomboidal  in  shape,  and 
ornamented  with  delicate  radiating  lines. 

An  impression  of  the  adipose  dorsal  fin  has-been  observed  in  this

Genus  EURYPHOLIS,  Pictet. 

[Poiss.  Poss.  Mont  Liban,  1850,  p.  28.] 

Syn.  Saiirorhamphus,  J.  J.  Heckel,  Denkschr.  k.  Akad.  Wiss.,  math.- 
naturw.  Cl.  vol.  i.  1850,  p.  217  (inaccurate  definition). 

Form  and  proportions,  arrangement  of  jaws  and  dentition  as  in 
Enchodus.  Cranial  roof  almost  completely  covered  with  tubercular 
ornament ;  cheek-plates  comprising  the  hinder  portion  of  a  small 
circumorbital  series,  and  large  posterior  suborbitals,  also  orna¬ 
mented  with  tubercles.  Preoperculum  narrow  and  deep,  its  lower 
end  expanded  into  a  small,  stout,  posteriorly  directed  spine  ; 
operculum  triangular  in  shape,  its  transverse  inner  ridge  extending 
from  the  point  of  suspension  to  the  hinder  angle  ;  branchiostegal 
rays  about  15  in  number.  Yertebrse  approximately  40  in  number, 
the  centra  slender  and  much  constricted.  A  large  triangular  orna¬ 
mented  dermal  plate  fixed  to  the  lower  half  of  the  clavicle ;  the 
pectoral  fin,  of  moderate  size,  arising  above  this  upon  the  flank  of 
the  fish ;  pelvic  fins  very  large  and  far  forwards.  Dermal  scutes 
well-developed,  some  slightly  overlapping,  and  all  ornamented  with 
tubercles  ;  three  or  four  large  median  scutes  in  series  between  the 
occiput  and  dorsal  fin,  and  smaller  scutes  along  the  course  of  the 
lateral  line,  but  none  enlarged  on  the  caudal  pedicle. 

Many  details  in  the  osteology  of  this  genus  are  illustrated  by  the 
specimens  of  the  typical  species  described  below.

Type.  Head  with  abdominal  region  ;  Geneva  Museum. 

The  type  species,  attaining  a  length  of  about  0-2.  Head  with 
opercular  apparatus  about  twice  as  long  as  its  maximum  depth, 
occupying  one  third  of  the  total  length  to  the  base  of  the  caudal 
fin.  Ornament  consisting  of  closely-arranged  rows  of  fine,  well- 
separated  tubercles,  covering  all  the  external  bones  and  scutes. 
The  large  palatine  tooth  smooth  and  inclined  a  little  forwards ; 
some  of  the  other  teeth  slightly  fluted  at  the  base  of  the  crown. 
Operculum  an  almost  equilateral  triangle  ;  spine  at  the  lower  end

ACTIXOPTERYGII. 


of  preoperculum  short  and  stout ;  postclavicular  plate  triangular, 
somewhat  longer  than  deep,  and  its  postero-superior  margin  ex¬ 
cavated.  Pectoral  fin  arising  just  above  the  postclavicular  plate, 
the  large  pelvic  fin  immediately  behind  this  plate  and  in  advance  of 
the  origin  of  the  dorsal  fin  ;  dorsal  fin  somewhat  deeper  than  long, 
comprising  12  rays,  and  the  distance  between  its  hinder  end  and 
the  caudal  fin  slightly  exceeding  that  between  its  origin  and  the 
occiput ;  anal  fin  smaller  than  the  dorsal,  at  least  as  long  as  deep, 
comprising  13  rays,  and  arising  much  nearer  to  the  caudal  than  to 
the  pelvic  fius.  Three  large  dorsal  plates  behind  the  occiput,  ovate 
in  form,  very  slightly  overlapping,  ornamented  with  closely- 
arranged  concentric  rows  of  tubercles,  and  not  quite  reaching  the 
dorsal  fin ;  lateral  scutes  much  smaller,  irregularly  triangular  and 
deeper  than  broad,  perforated  by  the  sensory  canal. 

Form.  Log.  Upper  Cretaceous  :  Hakel,  Mount  Lebanon,  Syria. 

49478.  A  vertically  crushed  specimen,  displaying  the  head  and 
opercular  bones  as  shown  in  PI.  XI.  fig.  7.  The  cranial 
roof  is  shown  partly  from  within,  partly  in  impression  of 
the  outer  ornamented  face  ;  but  it  merely  exhibits  the 
large  extent  of  the  frontals  (/r.),  not  distinctly  indicating 
the  other  elements.  The  extended  premaxilla 
deepened  in  front  and  tapering  behind,  is  conspicuous  on 
each  side  and  exhibits  the  single  series  of  small  slender 
teeth,  fixed  on  tumid  bases.  On  the  left  side  the  slender 
maxilla  (ma’.),  with  small  teeth  in  its  hinder  portion,  also 
seems  to  be  partly  preserved.  The  orbit  (o.)  is  bounded 
behind  by  a  chain  of  small,  tuberculated  circumorbital 
plates  (co.),  of  which  four  are  preserved while  the  whole 
of  the  cheek  between  these  and  the  preoperculum  is 
covered  by  posterior  suborbitals  (s.o.),  of  which  the  limits 
are  not  clear.  Both  mandibular  rami  are  exposed  from 
•within  and  exhibit  the  characteristic  teeth  on  tumid  bases, 
while  that  of  the  right  side  shows  two  irregular  promi¬ 
nences  of  bone  at  the  tapering  symphysis.  Each  ramus 
gradually  deepens  behind  and  seems  to  consist  of  two 
elements,  dentary  (d.')  and  articulo-angular  (ug.),  of  which 
the  limits  are  indicated  by  the  impression  of  the  tubercu¬ 
lated  outer  face  of  the  leftside.  The  preoperculum  {p.op.) 
'  is  a  thickened  vertical  rod,  almost  reaching  the  cranial 
roof  above,  and  terminated  below  by  the  short  and  stout 
posteriorly-directed  spine  ;  a  narrow  tuberculated  lamina 
extends  along  its  posterior  margin.  The  triangular  opei-

culam  {op.)  exhibits  its  thickened  inner  rib,  and  is  suffi¬ 
ciently  transparent  to  admit  of  the  radiating  lines  of  fine 
tubercles  on  its  outer  face  being  seen.  The  suboperculum 
{s.op.)  is  imperfectly  preserved  only  on  the  left  side;  its 
tubercular  ornament  is  arranged  in  almost  vertically 
directed  lines.  The  dorsal  scutes  {cl.s.)  are  exposed  from 
within,  and  immediately  behind  the  left  operculum  the 
inner  face  of  the  triangular  post-clavicular  plate  (p.cl.)  is 
also  shown.  One  pelvic  fin  (plv.)  is  preserved  behind. 
The  other  remains  are  too  imperfect  for  description.

while  the  third  and  fourth  show  the  large  anterior  tooth 
on  the  thickened  palatine  bone.  Lewis  Coll. 

P.  74.  Another  fine  specimen  in  side  view,  displaying  one  of  the 
pelvic  fins.  The  foremost  ray  of  this  fin  is  much  the 
stoutest,  closely  articulated  but  not  divided  distally ;  it  is 
also  the  shortest  ray,  and  the  others,  to  the  number  of 
about  seven,  gradually  increase  in  length.  Lewis  Coll.

is  filled  with  calcite,  which  proves  that  a  delicate  thread 
persisted  piercing  each  centrum.  This  and  the  third 
specimen  also  exhibit  the  peculiar  form  of  the  pelvic 
bones,  one  of  which  is  restored  in  the  diagram,  text- 
fig.  7.  The  main  portion  of  this  element  gradually 
expands  towards  its  anteriorly  directed  end;  it  is  con¬ 
tracted  presumably  at  the  point  of  origin  of  the  pelvic  fin, 
and  thence  sends  a  small  expanding  process  inwards  to 
meet  its  fellow  of  the  opposite  side.  Lewis  Coll.

Type.  Imperfect  fish  ;  Museum  of  Laibach,  Austria. 

The  type  species  of  the  so-called  Saurorhamphus,  attaining  a 
length  of  about  0'2.  Head  with  opercular  apparatus  occupying 
one  third  of  the  total  length  to  the  base  of  the  eaudal  fin. 
Ornament  apparently  as  in  E.  hoissieri.  Fins  almost  as  in  the 
latter,  but  abdominal  region  probably  somewhat  more  elongated. 
Four  large  dorsal  plates  behind  the  occiput,  ovate  in  form,  very 
slightly  overlapping,  ornamented  with  fine  tubercles,  and  not  quite 
reaching  the  dorsal -fin;  lateral  scutes  smaller,  irregularly  tri¬ 
angular,  and  notched  (perhaps  also  perforated)  by  the  sensory  canal. 

The  erroneous  restoration  by  Heckel  gives  a  very  false  idea  of 
this  fish.  Every  feature  in  its  osteology  hitherto  definitely  dis¬ 
covered,  suggests  that  its  reference  to  the  genus  Eurypholis  is 
correct.

Trunk  much  elongated,  both  this  and  the  head  laterally  com¬ 
pressed.  Ja’ws  and  dentition  as  in  EncJiodus  and  Euryjjholis. 
Vertebrae  at  least  70  in  number,  nearly  half  abdominal ;  the  centra 
longer  than  deep,  constricted  mesially,  and  strengthened  by  at  least 
one  lateral  longitudinal  ridge.  All  except  the  foremost  rays  of

opercular  apparatus  nearly  eight  times  in  the  total  length  of  the 
fish.  Enlarged  teeth  longitudinally  striated.  Vertebrae  75  in 
number,  about  32  referable  to  the  abdominal  region ;  the  centra 
slightly  pierced  by  persistent  notochord.  Pelvic  fins  arising  slightly 
behind  the  middle  point  between  the  pectoral  and  anal  fins ;  dorsal 
fin  arising  considerably  behind  the  anal,  but  opposed  to  part  of  the 
anterior  half  of  the  latter,  comprising  one  spine  and  8  divided  rays, 
the  spine  not  much  shorter  than  the  first  divided  ray  ;  anal  fin 
extending  along  nearly  the  whole  of  the  caudal  region,  with  about 
46  well-spaced  divided  rays,  apparently  no  anterior  spinous  rays. 
Dorsal  scutes  perhaps  about  6  in  number,  ornamented  with  fine 
radiating  ridges.

Trunk  deeply  fusiform,  both  this  and  the  head  laterally  com¬ 
pressed.  Cranial  roof  exhibiting  a  median  longitudinal  depression, 
its  lateral  and  occipital  margins  ornamented,  like  the  other  external 
bones,  with  ridges  and  tubercles  of  ganoine.  Mandible  a  little 
prominent,  with  several  rows  of  recurved  conical  teeth,  irregular  in 
size  and  arrangement ;  premaxilla  long  and  slender,  with  two  or 
more  rows  of  minute  teeth  ;  maxilla  long  and  slender,  underlapped 
by  the  premaxilla  for  the  greater  part  of  its  length,  but  entering 
the  gape  behind,  where  it  bears  a  spaced  series  of  relatively  large 
conical  teeth  pointing  forwards;  a  conspicuous  supramaxilla  present; 
the  comparatively  stout  palatine  and  ectopterygoid  bones  bearing  a 
close  series  of  acute,  laterally- compressed  teeth,  which  are  largest 
in  the  middle  and  diminish  towards  each  extremity ;  no  teeth 
barbed.  Preoperculum  very  narrow  and  deep,  with  a  conspicuous 
posteriorly-directed  spine  at  its  lower  end  ;  operculum  strengthened 
on  the  inner  side  by  a  ridge  extending  almost  horizontally  back¬ 
wards  to  its  postero-inferior  angle ;  branchiostegal  rays  about  15  in 
number.  Yertebrse  from  35  to  45  in  number,  the  centra  at  least  as 
long  as  deep,  much  constricted  mesially  and  somewhat  strengthened 
with  small  longitudinal  ridges.  Fin-ray^s  robust  and  all  articulated, 
mostly  also  subdivided  distally ;  no  fin-rays  excessively  elongated. 
Paired  fins  large,  the  pelvic  pair  not  much  smaller  than  the 
pectorals;  the  short  dorsal  fin  within  the  anterior  half  of  the  trunk; 
anal  fin  relatively  small  and  remote  ;  caudal  fin  deeply  forked.  A 
regular  squamation  of  very  small  scales,  the  exposed  area  of  each 
quadrangular  in  shape ;  no  enlarged  scutes.

Type.  Imperfect  fish  ;  Brighton  Museum. 

The  type  species  of  the  so-called  Pomognathus.,  attaining  a  length 
of  about  0‘4.  Length  of  head  with  opercular  apparatus  much 
exceeding  the  maximum  depth  of  the  trunk,  which  is  probably 
contained  about  four  times  in  the  length  from  the  pectoral  arch  to 
the  base  of  the  caudal  fin.  Length  of  mandible  somewhat  exceeding 
the  depth  of  the  head  at  the  occiput ;  operculum  considerably 
deeper  than  broad ;  the  infero-posterior  spine  of  the  preoperculum 
short,  stout,  and  ornamented  with  tubercles.  The  external 
tubercular  ornament  very  fine,  arranged  in  more  or  less  radiating 
lines  on  the  sides  of  the  cranial  roof,  the  supramaxilla,  mandible, 
opercular  apparatus,  clavicle  and  supraclavicle.  The  stouter  rays 
of  the  paired  and  dorsal  fins  also  ornamented  with  longitudinal 
series  of  verv  fine  tubercles.  Yertebrse  about  45  in  number. 

The  squamation  of  this  species  is  unknown,  probably  on  account 
of  the  soft  nature  of  the  chalky  matrix  in  which  the  specimens  are 
preserved.

diagnosis.  The  total  number  of  vertebrae  is  shown  to  be 
about  45,  and  of  these  the  21  caudals  are  well  preserved. 
Fragments  of  all  the  fins  except  the  anal  are  distinguish¬ 
able.  Purchased,  1872. 

32336.  Imperfect  head  and  abdominal  region,  with  the  greater  part 
of  the  dorsal  and  paired  fins ;  Lower,  Chalk,  Maidstone. 
The  fossil  is  broken  across  at  the  back  of  the  head,  and 
the  opercular  apparatus  thus  destroyed  behind  the  pre¬ 
operculum.  The  cranial  roof  is  flattened,  constricted 
behind,  widest  at  the  hinder  border  of  the  orbits,  and 
marked  by  a  sharp  median  depression  between  the  orbits. 
The  very  large  froutal  bones  extend  almost  to  the 
occipital  border,  and  are  smooth  in  the  middle  portion 
which  passes  into  the  interorbital  depression,  but  are 
marked  with  the  characteristic  ornament  in  the  outer  or 
lateral  portion.  Anteriorly  they  unite  in  a  suture  with 
the  short  and  broad,  smooth  mesethmoid  bone ;  antero- 
laterally  they  are  overlapped  by  the  nasal  bones.  The 
latter  elements  are  well  preserved,  each  being  shown  to 
be  antero-posteriorly  elongated,  almost  ovate  though 
pointed  behind,  and  very  conspicuously  ornamented  with 
radiating  series  of  tubercles.  The  otic  region  is  too 
imperfect  for  description,  and  there  are  no  traces  of 
cheek-plates ;  but  in  side-view  there  are  recognisable 
remains  of  the  jaws.  The  triangular  metapterygoid  is 
completely  displayed,  but  the  remainder  of  the  pterygo¬ 
palatine  arcade  is  obscured  except  at  its  upper  border. 
The  very  long  and  slender  premaxilla  is  imperfect  in 
front,  but  exhibits  the  characteristic  fine  tubercular 
ornament  in  its  hinder  two  thirds,  while  the  oral  margin 
still  bears  some  of  the  minute  teeth.  The  maxilla,  though 
fractured,  is  preserved  for  the  greater  part  of  its  length, 
underlapped  more  than  halfway  by  the  premaxilla ;  and 
its  hinder  third  exhibits  some  of  the  large  and  charac¬ 
teristic  spaced  teeth,  which  are  inclined  with  the  point 
forwards.  Above  the  hinder  third  of  the  maxilla  is 
the  highly  ornamented  supraraaxilla,  antero-posteriorly 
elongated,  pointed  in  front  and  rounded  behind.  The 
mandible  is  crushed  at  the  symphysis  and  otherwise 
fractured,  but  the  suture  between  the  dentary  and 
angular  is  distinct,  and  the  fine  tubercular  ornament  is 
shown  to  cover  the  lower  portion  of  both  elements,  being 


'-y^^'*'''^  cu.^^  y^'  ^ T/- .

absent  only  in  the  area  apparently  overlapped  by  the 
upper  jaw.  The  course  of  the  sensory  canal  on  the 
angular  and  dentary  is  marked  by  a  deep  open  groove. 
The  preoperculum  is  narrow  and  deep,  with  the  long  axis 
vertical ;  and  its  finely  tuberculated  lower  end  is  scarcely 
bent  forwards,  being  produced  instead  backwards  into  a 
short  blunt  spine,  which  is  incomplete  at  the  point  in  the 
fossil.  Comparatively  slender  and  well-spaced  branchio- 
stegal  rays  are  shown  beneath  the  hinder  end  of  the 
mandible,  perhaps  eight  or  nine  in  number.  The  vertebral 
centra  are  much  constricted,  apparently  strengthened 
only  by.  one  ridge  on  each  side,  with  which  the  somewhat 
expanded  head  of  the  rib  articulates.  The  neural  arches 
are  small  and  low  laminar  expansions,  each  extending 
along  the  anterior  half  of  a  centrum  and  bearing  at  its 
postero-superior  angle  the  long  and  slender  neural  spine. 
The  imperfect  remains  of  the  clavicle  exhibit  a  large  inner 
lamina  nearly  at  right-angles  to  the  more  delicate  lamina 
in  the  plane  of  the  fiank;  and  the  pectoral  fin  is  shown 
to  be  relatively  large,  with  at  least  12  stout  rays,  which 
are  partly  ornamented.  The  pelvic  fins  are  also  indicated 
as  stout  and  far  forwards,  with  antero-posteriorly  elongated 
triangular  supports.  The  anterior  rays  of  the  dorsal  fin 
are  shown  to  be  very  stout,  ornamented  with  fine  tubercu- 
lations  and  longitudinal  rugae  ;  all  are  imperfect  distally, 
but  the  foremost  is  shown  to  be  articulated  towards  the 
end,  while  the  second  and  doubtless  the  others  are  both 
articulated  and  divided  distally.  Purchased.,  1857.

imperfect  only  at  its  hinder  end.  It  is  shown  to  be  a 
slender  bone,  slightly  deepened  in  front  and  curved

inwards  to  the  ethmoidal  region,  also  slightly  deepened 
again  in  its  hinder  third,  where  it  bears  the  spaced  series 
of  comparatively  large  teeth.  Its  lower  margin  is 
ornamented  with  fine  tubercles  throughout  its  length* 
The  supramaxilla,  premaxilla,  and  dentary  are  also  im¬ 
perfectly  preserved ;  and  part  of  the  thickened  ecto- 
pterygoid  is  exposed  within.  The  lower  end  of  the 
preoperculum  bears  the  usual  posterior  spine,  and  its 
fine  tubercular  ornament  extends  in  a  narrow  band  at 
least  halfway  up  the  ascending  limb  of  the  bone.  The 
operculum  is  ornamented  with  close  radiating  lines  of  fine 
tubercles ;  and  the  more  delicately  marked  suboperculum 
is  shown  to  be  relatively  small.  The  clavicle  is  partly 
ornamented  with  elongated  tubercles  in  radiating  series ; 
and  the  supraclavicle  exhibits  longitudinal  rows  of 
tubercles  in  its  exposed  hinder  half.  Enniskillen  Coll.

species. 

Form.  Log.  Cretaceous  :  Island  of  Lesina,  Dalmatia. 

P.  7452.  Imperfect  fish  wanting  the  caudal  fin,  slightly  larger 
than  the  type  specimen.  Among  the  crushed  remains  of 
the  head  may  be  observed  impressions  of  the  characteristic 
teeth  of  the  ectopterygoid ;  there  are  also  traces  of  the 
fine  tubercular  ornament  of  the  mandible.  The  vertebrae 
are  rather  large,  and  seem  to  have  been  about  35  in  total 
number.  The  fins  are  very  imperfect,  and  the  number  of 
their  rays  cannot  be  counted  ;  but,  so  far  as  preserved, 
they  seem  to  agree  with  those  of  H.  microlepis.  There 
are  also  obscure  indications  of  the  characteristic  minute 
scales.  Parchased,  1895. 

P.  7453.  Ifore  imperfect  specimen,  displaying  the  fine  tubercular

Trunk  elongate-fusiform.  Cranium  as  in  Enchodus.  Premaxilla 
in  the  form  of  a  vertical  lamina,  externally  ornamented,  and  either 
toothless  or  vrith  a  series  of  minute  teeth ;  maxilla  long  and  styli- 
form,  similarly  either  toothless  or  with  minute  teeth  where  it 
enters  the  oral  margin ;  ectopterygoid  bearing  a  single  spaced 
series  of  acute,  laterally-compressed  teeth,  which  are  largest  in 
front  and  sometimes  exhibit  a  single  posterior  barb  towards  their 
apex  ;  palatine  with  a  double  longitudinal  series  of  teeth,  none 
barbed,  the  largest  behind  ;  dentary  thin,  but  so  bent  that  it  has  a 
wide  horizontal  extent,  with  a  close  series  of  minute  teeth  on  its 
extreme  outer  margin,  another  close  series  of  larger  teeth  withiii 
this,  and  a  third  inner  series  of  relatively  large  recurved  teeth,  well 
spaced,  and  not  barbed  at  the  apex.  Operculum  strengthened  on 
the  inner  side  by  a  ridge  extending  horizontally  backwards  from 
the  point  of  suspension.  Vertebrae  from  50  to  60  in  number,  about 
half  being  caudal;  the  centra  at  least  as  long  as  deep,  much 
constricted,  and  marked  with  fine  irregular  longitudinal  ridges. 
A  series  of  large  dermal  scutes  along  the  dorsal  ridge  between  the 
occiput  and  the  dorsal  fin ;  smaller  scutes  along  the  course  of  the 
lateral  line. 

One  specimen  of  the  trunk  hypothetically  ascribed  to  the  so-

Type.  Imperfect  ectopterygoid  ;  British  Museum. 

The  type  species,  Dot  satisfactorily  definable,  with  cranium 
attaining  a  length  of  about  0T5.  Maximum  width  of  cranium 
slightly  exceeding  one  third  its  length,  and  premaxilla  ornamented 
with  radiating  tuberculated  ridges.  All  the  teeth  of  the  ecto- 
ptervgoid,  except  the  few  small  ones  posteriorly,  moderately  slender 
and  slightly  barbed;  the  largest  tooth  of  the  inner  mandibular 
series  situated  within  the  anterior  half  of  the  dentary.

P.  5491.  Imperfect  skull  and  mandible,  noticed  by  the  present 
writer,  loc.  cit.  p.  317  ;  Chalk,  Lewes.  The  specimen  is 
damaged  by  an  oblique  fracture,  and  the  rostral  region  of 
the  cranium  is  obscure  ;  but  the  I'routal  bones  are  well 
displayed  and  shown  to  extend  close  to  the  occipital 
border.  Only  a  trace  of  the  small  supraoccipital,.  with  its 
hinder  keel,  is  preserved.  There  is  a  shallow,  antero- 
posteriorly  elongated  fossa  above  the  otic  region  on  each 
side.  ^Fragmentary  remains  of  the  premaxilla  on  each 
side  prove  it  to  have  been  an  antero-posteriorly  elongated 
laminar  bone,  bent  inwards  above  on  its  long  axis,  and 

I 

ornamented  externally  with  tuberculated  radiating  ridges. 
The  long  and  slender  maxilla,  which  is  almost  smooth,  is 
nearly  complete  on  the  left  side,  and  extends  forwards 
above  the  premaxilla  to  about  the  middle  point  of  the 
latter.  Neither  the  maxilla  nor  the  premaxilla,  as  pre¬ 
served,  exhibits  any  indications  of  teeth.  The  imperfect 
mandible  is  seen  from  beneath,  and  two  of  its  large 
recurved  teeth  are  exposed.  There  are  also  remains  of 
the  pterygo-palatine  arcade,  with  several  of  the  character¬ 
istic  barbed  teeth,  and  with  marks  of  the  oval  bases 
of  attachment  of  similar  teeth  which  have  been  broken 
away.  The  slender  ceratohyal  is  preserved  on  the  left 
side ;  while  immediately  above  it  is  exposed  part  of  a 
laminar  bone,  probably  entopterygoid,  bearing  clustered 
minute  teeth..  Enniskillen  Coll.

Type.  Imperfect  palatine  bone  ;  Cope  Collection. 

The  type  species  of  the  so-called  Empo,  'with  skull  from  0-3  to 
0'4  in  length.  The  sides  of  the  cranial  roof  and  the  outer  face  of 
the  mandible  ornamented  with  numerous  and  closely -arranged 
sharp  ridges,  mostly  radiating  and  bearing  a  series  of  minute 
tubercles  ;  these  ridges  on  the  dentary  bone  radiating  from  the 
symphysis,  on  the  articulo-angular  bone  radiating  from  the 
mandibular  articulation.  Maximum  width  of  cranium  across  frontal 
region  about  half  its  length  ;  maximum  depth  of  mandibular  ramus 
contained  six  or  seven  times  in  its  length.  Premaxilla  a  very 
thin  lamina  with  a  regular  and  uniform  series  of  sharply  recurved 
teeth,  as  small  as  the  outermost  teeth  of  the  dentary;  palatine 
inner  teeth  in  close  series,  half  as  thick  at  the  base  as  the  large 
outer  teeth,  which  are  inclined  somewhat  outwards  but  strongly 
recurved  towards  the  apex ;  ectopterygoid  teeth  few  and  large,  the 
two  foremost  being  the  largest,  compressed  to  a  sharp  edge  in  front 
but  not  behind ;  mandibular  teeth  also  compressed  to  a  sharp  edge 
only  on  their  anterior  aspect  and  strongly  recurved.  Operculum 
considerably  broader  than  deep.  Dorsal  scutes  in  front  of  dorsal 
fin  ovate  and  produced  into  a  slender  point  in  front,  ornamented 
externally  with  radiating  series  of  very  fine  tubercles.

from  above,  displaying  the  large  frontals  (/r.)  but  crushed 
at  the  occiput  and  wanting  the  ethmoidal  region.  The 
remains  of  the  jaws  are  displaced  below  and  to  the  left  of 
the  cranium.  The  delicate  laminar  premaxilla  {pmoc.), 
with  its  small  recurved  teeth,  is  seen  in  front.  The  left 
palato-pterygoid  arcade  {pt.)  is  imperfectly  displayed,  with

some  of  its  large  teeth ;  and  the  two  dentary  bones  (d.) 
of  the  mandible  occur  deeper  in  the  matrix,  that  of  the 
right  side  being  partly  obscured.  The  left  articulo- 
angular  bone  (ag.)  is  displaced,  and  also  partly  covered 
by  other  fragments.  The  imperfect  left  operculum  (op.) 
is  distinguishable  from  its  inner  face,  but  is  turned  so 
that  its  horizontal  axis  is  directed  downwards.  Five  of 
the  anterior  vertebral  centra  are  exhibited,  showing  the 
deep  infero-lateral  pits  for  the  ribs.  Further  back  are 
other  centra,  beneath  which  the  somewhat  robust  ribs  are 
also  preserved.  There  are  obscure  remains  of  the 
pectoral  arch,  with  traces  of  very  stout  pectoral  fin-rays 
(pet.) ;  and  there  is  only  a  fragment  of  one  other  fin,  the 
dorsal,  which  has  remarkably  robust  supports,  but  is  not 
shown  in  the  figure.  Five  of  the  characteristic  scutes  (5.), 
partly  displaced,  are  observed  on  the  ridge  of  the  back  in 
front  of  the  dorsal  fin,  the  two  foremost  being  shown 
chiefly  as  an  impression  of  the  outer  face. 

Purchased,  1891. 

P.  6339.  Scattered  remains  of  head  and  anterior  abdominal  region, 
sketched  in  outline  in  the  accompanying  fig.  9.  The 
imperfect  cranium,  wanting  the  ethmoidal  region,  is 
exposed  from  beneath,  and  the  well-preserved  basi- 
occipital  (h.  oec.)  demonstrates  the  absence  of  a  basicranial 
canal.  The  otic  region  is  shown  to  be  well  ossified,  and 
bounded  in  front  by  a  prominent  sphenotic  or  post-frontal 
(sp.o,).  Further  forwards  there  are  remains  of  the  large 
frontals  (fr.).  The  displaced  jaws  are  observed  below 
the  overturned  cranium.  The  imperfect  right  palatine 
(r.pl.)  and  anterior  end  of  ectopterygoid  (r.ecpt.)  are 
partly  obscured  by  the  fragments  of  the  frontal  region. 
Next  below  is  part  of  one  of  the  thin  laminar  premaxillae 
(pmx.),  bearing  the  characteristic  regular  series  of  small 
recurved  teeth.  Then  follow  remains  of  the  left  pala¬ 
tine  (l.pl.)  and  ectopterygoid  (l.ecpt.),  displaying  the 
characteristic  dentition.  The  hinder  portion  of  the 
ectopterygoid  is  toothless,  and  curves  downwards  as  it 
approaches  the  quadrate  (qu.) ;  while  it  seems  to  be 
bounded  above  by  the  entopterygoid  (l.enjgt.),  which 
exhibits  the  bases  of  an  antero-posteriorly  elongated 
cluster  of  minute  teeth.  The  fragmentary  hinder  portion 
of  the  right  ectopterygoid  (r.ecpt.)  partly  overlies  the  left

somewhat  less  than  half  the  length  of  the  trunk  from  the  pectoral 
arch  to  the  base  of  the  caudal  fin;  maximum  depth  of  trunk 
contained  about  seven  times  in  the  same  measurement.  Pelvic 
fins  arising  somewhat  in  advance  of  the  middle  point  of  the  trunk, 
opposite  the  hinder  part  of  the  dorsal  fin,  which  comprises  about 
16  rays  and  is  completely  within  the  anterior  half  of  the  trunk  ; 
anal  fin  comparatively  low  and  small,  with  about  14  rays,  arising 
much  nearer  to  the  caudal  fin  than  to  the  pelvic  pair.  Lateral 
dermal  scutes  between  40  and  50  in  number,  and  the  largest  about 
five  times  as  deep  as  broad,  with  the  forwardly  directed  portion 
above  the  lateral  line  two  thirds  as  deep  as  the  portion  below  it ; 
the  hinder  margin  deeply  pectinated,  though  rather  irregular,  and 
the  uppermost  pectinations  the  longest ;  the  anterior  portion 
marked  with  delicate  and  irregular  vertical  rugge.

P.  9149.  Another  large  fish  vertically  crushed  and  partly  in

cranial  roof  seems  to  indicate  a  median  hollowing  and  a 
lateral  ornamentation  of  radiating  lines  and  tubercles  ; 
while  the  ethmoidal  region  is  clearly  short  and  broad, 
though  acutely  pointed  in  front.  The  jaws  are  very 
imperfect,  but  they  are  proved  to  have  been  delicate  ; 
while  the  only  remains  of  dentition  are  one  slender 
lanceolate  tooth  in  front  and  clustered  minute  blunt 
teeth  behind.  Posterior  to  the  outwardly  crushed  cheek 
on  either  side  there  are  remains  of  the  narrow  pre¬ 
operculum  and  the  well-developed  operculum ;  and  the 
latter  plate  is  shown  to  have  been  strengthened  not  only 
bv  the  thickening  of  its  anterior  border,  but  also  by 
a  horizontally-directed  ridge  on  its  inner  face,  while  the 
upper  half  of  its  outer  face  is  marked  with  numerous 
delicate  radiating  lines  which  are  partly  tuberculated. 
The  vertebral  column  is  imperfectly  preserved,  comprising 
delicate  constricted  centra,  longer  than  deep,  each 
distinctly  pierced  for  the  persistence  of  the  continuous 
notochord.  The  ribs  seem  to  be  short  and  comparatively

stout,  not  supported  by  transverse  processes.  The  upper 
and  lower  limbs  of  the  bent  clavicle  are  equal  in  size ; 
and  one  of  the  pectoral  fins,  which  is  displaced  and 
apparently  incomplete,  shows  remains  of  ten  rays.  The 
lateral  scutes  are  very  well  exhibited,  and  each  is  pierced 
by  a  tubular  perforation  for  the  passage  of  the  sensory 
canal  of  the  lateral  line.  These  scutes  begin  to  appear 
immediately  behind  the  pectoral  arch  and  extend  regularly 
to  the  base  of  the  caudal  fin  ;  at  least  45  are  indicated  on 
each  side,  and  the  series  is  probably  not  quite  complete 
behind.  Presented  hy  A.  S.  Woodward,  Esq.,  1898.

The  type  species  of  the  so-called  Apateopholis^  attaining  a  length 
of  about  0"35.  Length  of  head  with  opercular  apparatus  nearly 
equalling  the  length  of  the  trunk  from  the  pectoral  arch  to  the  base 
of  the  caudal  fin ;  maximum  depth  of  trunk  contained  four  times 
in  the  same  measurement.  Pelvic  fins  arising  just  behind  the 
middle  point  of  the  trunk,  opposite  the  hinder  part  of  the  dorsal 
fin,  which  comprises  about  20  rays  and  is  almost  completely  within 
the  hinder  half  of  the  trunk;  anal  fin  comparatively  low  and 
extended,  with  about  17  rays,  arising  nearer  to  the  pelvic  pair  than 
to  the  caudal  fin.  Lateral  dermal  scutes  very  thin,  between  40 
and  50  in  number,  and  the  largest  about  four  or  five  times  as  deep 
as  broad,  ornamented  with  extremely  delicate  concentric  ridges, 
sometimes  subdivided  into  tubercles,  following  the  lines  of  growth  ;

Syn.  Dermatoptyclms,  W.  von  der  March,  Palaeontogr.  vol.  xv.  1868, 
p.  287. 

Head  large,  and  the  maximum  depth  of  the  trunh  at  the  origin 
of  the  dorsal  fin.  Mandibular  suspensorium  nearly  vertical ;  jaws 
moderately  stout,  and  maxilla  expanded  behind ;  teeth  very  minute ; 
cheeh  scaly.  Branchiostegal  rays  about  9  in  number.  Vertebrae 
between  30  and  40  in  number,  about  half  being  caudal ;  the  centra 
longitudinally  striated  and  not  longer  than  deep ;  ribs  delicate.  No 
fin-rays  elongated,  but  two  or  three  in  front  of  the  median  fins 
undivided  and  spinous.  Pectoral  fins  very  delicate  and  small,  well 
above  the  ventral  border;  pelvic  fins  well  developed,  with  about 
7  rays,  opposed  to  the  dorsal  fin,  which  is  nearly  median  a'nd 
comprises  from  10  to  18  rays ;  anal  fin  behind  the  dorsal,  at  least

as  deep  as  long,  with  about  10  rays ;  caudal  fin  slightly  forked. 
Scales  large  and  uniform,  finely  serrated  on  the  hinder  border,  not 
deepened  or  thickened  along  the  course  of  the  lateral  line. 

So  far  as  can  be  determined  from  the  skeleton,  this  genus 
appears  to  differ  from  the  surviving  Scojpelus  only  in  the  compara¬ 
tively  small  size  and  remote  situation  of  the  anal  fin,  and  in  the 
serrated  character  of  the  scales.

Type.  Nearly  complete  fish  ;  Palaeontological  Museum,  Munich. 

The  type  species,  attaining  a  length  of  about  0’2,  but  usually 
smaller.  Length  of  head  with  opercular  apparatus  considerably 
exceeding  the  maximum  depth  of  the  trunk,  and  equalling  at  least 
half  the  length  of  the  trunk  from  the  pectoral  arch  to  the  base  of 
the  caudal  fin.  Vertebrae  about  32  in  number.  Pelvic  fins  arising 
opposite  the  origin  of  the  dorsal,  much  nearer  to  the  pectorals  than 
to  the  anal ;  dorsal  fin  about  as  deep  as  the  trunk  at  its  origin, 
comprising  12  or  13  rays,  of  which  the  two  foremost  are  short  and 
spinous,  the  third  the  longest  and  articulated  though  not  divided 
distally,  and  the  others  both  articulated  and  divided  distally ;  anal 
fin  resembling  the  dorsal,  but  comparatively  small  and  remote,  with 
only  10  rays.  Serrations  of  scales  deep  and  conspicuous.

A  small  robust  species,  attaining  a  length  of  about  0*1.  Length 
of  head  with  opercular  apparatus  not  exceeding  the  maximum

Vertebrae  30  in  number.  Pins  as  in  the  type  species,  except  that 

the  dorsal  comprises  only  10  or  11  rays.  Serrations  of  scales  deep

Form.  ^  Log.  Upper  Cretaceous  :  Sahel  Alma,  Mt.  Lebanon, 

48123.  The  type  specimen,  shown  of  the  natural  size  in  PI.  XVI. 

fig.  2.  The  open  mouth  displays  very  minute  teeth,  and 
its  upper  margin  is  clearl}’'  formed  by  the  slender  ex¬ 
tended  premaxilla.  The  maxilla,  with  its  triangular 
distal  expansion,  is  seen  in  imperfect  impression  above 
the  premaxiUa.  The  stout  parasphenoid  marks  the  base 
of  the  cranium.  The  vertebrae  are  clearly  not  more  than 
30  in  number,  and  of  these  about  15  may  be  counted  as 
caudal.  The  anterior  abdominal  region  is  much  disturbed, 
and  the  paired  fins  are  represented  solely  by  an  impression 
of  the  6  rays  of  one  of  the  pelvic  pair.  The  dorsal  fin 
comprises  two  comparatively  short  and  slender  spines, 
then  the  longest  ray,  articulated  distally  but  not  sub¬ 
divided,  and  then  7  or  8  articulated  and  divided  rays. 
The  anal  fin  is  relatively  very  small,  apparently  with  8  or 
9  rays,  but  imperfectly  preserved.  The  caudal  fin  is  also 
imperfect,  but  distinctly  forked.  Where  the  scales  are 
partially  broken  away,  their  posterior  serrations  are 
especially  well  seen  upon  the  pale-coloured  matrix.

P.  4482.  Another  imperfect  specimen,  represented  of  the  natural 
size  in  PI.  XVI.  fig.  3.  The  head  is  crushed  backwards 
and  the  mouth  widely  opened,  while  the  displaced  hyoid 
apparatus  bears  the  characteristic  branchiostegal  rays. 
29  or  30  vertebrje  can  be  distinctly  counted,  and  the  con¬ 
stricted  centra  seem  to  have  been  marked  with  fine 
longitudinal  ridges.  One  of  the  small,  delicate  pectoral 
fins  is  partly  seen;  while  the  comparatively  large  and 
robust  pelvic  fins,  each  with  6  or  7  rays,  are  also  preserved 
beneath  the  origin  of  the  dorsal.  The  latter  fin  is  well 
displayed  ;  and  the  anal  fin  seems  to  exhibit  8  stout  rays. 
The  lobes  of  the  caudal  fin  are  imperfect  distally.  The

P.  8682.  Type  specimen,  shown  of  the  natural  size  in  PI.  XII. 

fig.  5.  The  mouth  is  closed,  but  the  form  of  the  mandible 
is  distinct,  while  the  characteristic  premaxilla  and  maxilla 
are  well  displayed  above  it.  The  vertebral  column  is

a  similar  number  can  be  counted  in  the  caudal  region. 
One  of  the  small,  delicate  pectoral  fins  is  imperfectly 
shown;  and  there  are  obscure  traces  of  the  relatively 
large  and  stout  pelvic  fins.  The  dorsal  fin  is  imperfect

about  10  rays,  the  length  of  the  longest  approximately 
equal  to  the  depth  of  the  trunk  at  its  insertion.  The 
anal  and  caudal  fins  are  also  imperfect.  The  large,  very 
finely  serrated  scales  (fig.  5  a)  are  especially  well  seen  in 
the  caudal  region.  Purchased,  1897. 

The  following  specimens  seem  to  be  referable  to  an  undetermined 
species  of  Sardinioides,  and  are  interesting  as  showing  the  small 
parietal  bones  meeting  in  the  middle  line  of  the  skull : —

median  ethmoid  projects  forwards  in  front.  The  parietals 
are  very  small,  but  clearly  overlie  the  supraoccipital  and 
meet  in  the  middle  line.  There  is  a  large  supraorbital 
bone  on  each  side.  The  characteristic  jaws  and  scaly 
cheeks  are  seen,  while  the  opercular  bones  exhibit  the 
same  rugosity  as  the  cranial  roof.  A  few  vertebral 
centra  are  exposed,  and  there  are  remains  of  the  pectoral, 
pelvic,  and  dorsal  fins.  The  large,  feebly  ctenoid  scales 
are  scattered.  Ennishillen  Coll.

An  examination  of  the  undermentioned  specimen  has  convinced 
the  present  writer  that  this  must  also  be  referred  to  the  genus 
Sardinioides,  the  typical  scales  being  clearly  distinguishable,  and 
the  vertical  banding  of  the  fossil  being  due  to  the  state  of  pre¬ 
servation  of  the  muscle-plates  : —

49565.  Imperfect  fish  about  0*09  in  length,  deepened  by  distortion. 

The  dorsal  fin  is  very  clearly  shown,  as  described  in  the 
generic  diagnosis ;  and  in  front  of  this  fin  there  are 
evidently  free  neural  spines,  somewhat  thickened,  ex¬ 
panded  and  truncated  distally.  The  course  of  the  lateral 
line  is  marked  upon  the  scales  just  above  the  vertebral 
column.  Lewis  Coll. 

49562.  Equally  small  fish,  somewhat  imperfect  and  deepened  by 
distortion,  but  displaying  most  of  the  generic  and  specific 
characters,  shown  of  the  natural  size  in  PI.  XVI.  fig.  I. 
The  head  is  clearly  short  and  deep,  the  opercular  apparatus 
also  short  and  deep,  and  the  clavicle  rather  stout.  Some 
of  the  ribs  are  seen  beneath  the  scales;  and  there  are 
similarly  indications  of  three  separated  neural  spines, 
thickened,  expanded,  and  truncated  distally,  in  front  of 
the  dorsal  fin.  The  neural  and  haemal  spines  of  the 
caudal  region  are  observed  to  be  very  stout.  The  cha¬ 
racteristic  dorsal  fin,  with  its  elongated  ray,  is  almost 
completely  shown  ;  and  there  are  fragmentary  remains  of 
all  the  other  fins.  The  course  of  the  lateral  line  is  partly 
marked  upon  the  scales  immediately  above  the  vertebrae.

Type.  Yearly  complete  fish  ;  Academy  of  Miinster. 

The  type  species,  attaining  a  length  of  about  0*08.  Length  of 
head  with  opercular  apparatus  scarcely  equalling  the  maximum 
dejjth  of  the  trunk,  and  contained  two  and  a  half  times  in  the 
length  from  the  pectoral  arch  to  the  base  of  the  caudal  fin.  Paired 
fins  nearly  equal  in  size,  the  distance  between  them  less  than  that 
between  the  pelvic  pair  and  the  anal;  dorsal  fin  occupying  about 
half  the  back,  arising  somewhat  in  front  of  its  middle  point,  and 
comprising  three  shore  and  two  long  undivided  rays,  followed  by 
24  divided  rays ;  anal  fin  nearly  similar  to  the  dorsal,  arising 
slightly  behind  the  latter,  and  comprising  two  short  and  one  long 
undivided  rays,  followed  by  about  24  divided  rays  ;  these  median 
fins  extending  close  to  the  caudal. 

As  already  remarked  by  von  der  Alarck  (loc.  cit.  1868),  the 
granulations  on  the  scales  mentioned  in  the  original  diagnosis  are 
due  to  accident  in  fossilisation.

midway  between  the  pectorals  and  the  anal ;  dorsal  fin  occupying 
about  one  third  of  the  back,  arising  opposite  the  pelvic  pair,  and 
comprising  17  or  18  divided  rays  in  addition  to  the  anterior 
undivided  rays ;  anal  fin  less  extended  than  the  dorsal,  but  with 
17  divided  rays,  and  arising  opposite  the  hinder  half  of  the 
dorsal ;  caudal  fin  apparently  more  deeply  forked  than  in  the  type 
species. 

Form.  Loc.  Upper  Cretaceous  :  Hakel,  Mt.  Lebanon. 

P.  4865.  The  t3*pe  specimen,  wanting  the  anterior  half  of  the  head,. 

and  measuring  about  0T05  in  length  from  the  pectoral 
arch  to  the  extremity  of  the  caudal  fin.  The  opercular 
apparatus  is  short  and  deep,  and  there  are  7  or  8 
branchiostegal  rays  in  advance  of  the  few  stout  rays 
noted  by  W.  vonderMarck  in  the  Westphalian  specimens.- 
The  axial  skeleton  and  fins  are  well  preserved,  except 
the  anterior  rays  of  the  dorsal  and  anal.  The  trunk  is 
slightly  deepened  by  crushing,  and  the  dorsal  margin  in 
front  of  the  fin  is  marked  by  curious  crimpings,  which 
are  suggestive  of  hard,  possibly  serrated  ridge-scales. 
The  large  smooth  scales  of  the  flank  displa.y  a  few 
radiating  grooves  on  their  covered  portion.  Lewis  Coll.

[Houv.  Eech.  Poiss.  Loss.  Mt.  Liban,  1866,  p.  78  (O2nsto2otery.v).^ 

Head  relatively  large  and  trunk  elongated,  its  maximum  depth 
at  the  opercular  apparatus.  Mandibular  suspensorium  much 
inclined  backwards,  and  cleft  of  mouth  wide,  extending  below  the 
orbit,  which  is  very  large  and  forwardly  placed ;  teeth  minute  ; 
gill-rakers  large  and  robust.  Vertebral  centra  not  longer  than 
deep,  longitudinally  striated,  between  50  and  60  in  total  number, 
about  half  caudal  and  half  abdominal ;  ribs  very  slender  ;  separate 
and  relatively  stout  sigmoidally  bent  neural  spines  in  the  abdominal 
region.  Pectoral  fins  elongated,  but  not  extending  beyond  the 
pelvic  pair,  inserted  close  to  the  ventral  border ;  pelvic  fins  some¬ 
what  smaller ;  dorsal  and  anal  fins  short-based,  very  deep  and 
acuminate,  the  former  placed  in  the  middle  of  the  back,  the  latter 
arising  opposite  its  hindermost  rays ;  caudal  fin  large,  deeply 
forked,  with  slender  acuminate  lobes.  Scales  thin,  but  apparently 
uniform  and  covering  the  whole  trunk.

[Fish  distorted  by  criisbing ;  Edinburgli  Museum.] 

Type.  Distorted  fish,  wanting  caudal  fin  ;  Geneva  Museum. 

The  type  species,  attaining  a  length  of  about  0*1.  Length  of 
head  with  opercular  apparatus  equalling  about  twice  the  maximum 
depth  of  the  trunk  and  contained  approximately  four  times  in  the 
total  length  of  the  fish.  Longest  ray  of  pectoral  fins  extending  to 
the  origin  of  the  pelvic  fins,  which  are  about  two  thirds  as  large 
as  the  pectorals  and  arise  midway  between  the  latter  and  the  anal; 
dorsal  fin  deeper  than  long,  with  about  11  rays,  its  origin  as  far 
from  the  occiput  as  is  its  termination  from  the  base  of  the  caudal 
fin ;  anal  fin  nearly  as  deep  as  the  dorsal  but  less  extended,  with 
only  about  8  rays,  arising  midway  between  the  pectorals  and  the 
caudal. 

The  fossilised  examples  of  this  fish  are  usually  much  distorted, 
but  its  general  characters  and  proportions  seem  to  be  correctly 
stated  in  the  above  diagnosis.  One  specimen,  evidently  shortened 
by  crushing,  is  described  by  Davis  under  a  distinct  specific  name,

The  last  species  is  recorded  from  the  Upper^Mioeene  of  Mondaino, 
Province  of  Forli,  Italy,  by  I.  Bonomi  (Bivista  Ital.  Paleont. 
vol.  ii.  1896,  p.  221),  who  has  founded  a  new  species  Anapterus 
macrocephalus  (loc.  cit.  p.  222,  pi.  v.  fig.  7)  on  another  in¬ 
determinable  fish.  Anapterus  toenia  is  an  undefined  name  given  by 
Bosniaski  (Proc.  Verb.  Soc.  Tosc.  Sci.  Nat.  vol.  i.  1878,  p.  xix)  to  a 
fish  from  the  Upper  Miocene  of  Gabbro,  Tuscany. 

The  following  remains  of  Scopelidae  with  slender  premaxilla  are 
not  generically  or  specifically  determined: — 

P.  4031,  P.  4766.  Small  elongated  fish,  in  counterpart ;  Upper 
Cretaceous,  Sahel  Alma,  Mt.  Lebanon.  The  jaws  are 
slender  and  the  mandible  bears  spaced  conical  teeth.  The 
paired  fins  are  rather  large.  The  dorsal  fin  is  median, 
deep,  and  short-based.  Lewis  Coll.

bears  large  spaced  conical  teeth  in  addition  to  minute 
teeth.  History  unhnown. 


Genus  APATEODUS,  novum. 

A  genus  known  only  by  parts  of  the  head,  which  is  elongated  and 
with  pointed  snout.  Parietal  bones  separated  by  the  supraoceipital, 
which  appears  in  the  middle  of  the  cranial  roof.  Premaxillee  very 
stout,  pointed  in  front  but  not  produced  forwards  in  advance  of  the 
ethmoidal  region  ;  teeth  large  in  the  middle  of  each  jaw,  laterally 
compressed,  and  fused  with  the  supporting  bone  at  their  tumid  base.

of  the  mandible  and  remains  of  three  vertebrm,  shown  of 
the  natural  size  in  PL  XIII.  fig.  3.  The  premaxilla 
{'pmoc.')  is  imperfect  at  each  end,  and  fractured  near  its 
middle  where  it  seems  to  be  accidentally  bent.  Immedi¬ 
ately  in  front  of  this  fracture,  the  largest  tooth  is  shown, 
with  its  distal  portion  obscured  by  the  remains  of  the 
mandible,  A  slightly  smaller  tooth  is  imperfectly  pre¬ 
served  a  little  further  back  ;  and  then  follow  three  or  four 
still  smaller  spaced  teeth,  which  are  much  laterally- com¬ 
pressed  and  vertically  striated  at  the  base.  The  dentary 
(cL)  is  considerably  fractured  and  broken  away  behind, 
but  its  outer  face  is  shown  to  have  been  smooth  and  rather 
tumid,  impressed  only  by  a  deep  longitudinal  groove  just 
below  its  upper  border.  Its  anterior  recurved  teeth  are 
preserved  on  both  sides  of  the  jaw,  gradually  increasing 
in  size  and  becoming  more  widely  spaced  backwards  ;  the 
very  large  middle  teeth  are  wanting  in  the  fossil ;  the 
hinder  teeth  are  proved  to  have  been  very  small.

individual,  that  of  the  right  side  shown  of  the  natural  size 
from  the  inner  aspect  in  PI.  XIII,  fig.  4.  Only  the 
anterior  half  of  the  bone  is  preserved,  and  it  seems  to 
represent  a  larger  fish  than  the  last  specimen.  It  tapers 
to  a  point  in  front,  while  its  inner  face  is  smooth  and 
flattened  for  articulation  with  the  elongated  ethmoidal 
region.  Its  oral  face  gradually  widens  backwards  and 
forms  a  gently  hollowed  trough,  which  is  filled  at  two 
points  by  the  tumid  bases  of  the  large  teeth.  Eoth  these 
teeth  are  well-preserved,  exhibiting  a  laterally  compressed, 
straight,  lanceolate  crown,  finely  striated  at  its  base.  The

sharp  edge  in  front  and  behind  ;  while  the  anterior  tooth 
is  rounded  behind,  with  a  sharp  edge  only  in  front. 
Between  the  large  teeth  there  are  also  traces  of  small  ones 
of  similar  form,  arranged  in  single  series  on  the  sharp 
outer  margin  of  the  hone.  One  of  these  small  teeth, 
preserved  on  the  left  premaxilla,  is  slightly  curved  in¬ 
wards  in  its  apical  portion.  Bemains  apparently  of  the 
attenuated  rostral  region  occur  above  the  right  premaxilla.

Type.  Small  head  ;  British  Museum. 

An  imperfectly  known  species,  the  mandible  probably  attaining  a 

length  of  about  0*15.  Two  teeth  on  the  anterior  half  of  the  pre¬ 
maxilla  much  enlarged ;  the  anterior  about  two  thirds  as  long  as

the  posterior  tooth,  and  the  length  of  the  latter  equalling  the  inter¬ 
space  between  the  two  teeth,  also  about  half  the  length  of  the  part 
of  the  premaxilla  in  front  of  its  insertion.  Maximum  depth  of 
mandible  equalling  about  one  fifth  of  its  length ;  dentition  occupy¬ 
ing  half  its  length,  with  two  relatively  large  teeth  of  about  equEil 
size  in  the  middle  of  the  series,  with  small  broad  teeth  behind,  and 
still  smaller  recurved  teeth  in  front.  Large  teeth  much  laterally 
compressed,  and  marked  with  very  fine  vertical  striations  in  the 
basal  portion. 

The  name  striatus  is  given  to  this  species,  because  it  seems 
probable  that  the  indeterminable  fragment  of  jaw  described  by 
Agassiz  as  Saurocephalus  striatus  is  the  hinder  part  of  a  large  pre¬ 
maxilla  of  the  same  form. 

Form.  Log.  Turonian  :  S.E.  England. 

49821.  The  type  specimen,  a  small  skull  and  mandible,  partly 
broken  and  distorted,  shown  from  both  sides  and  from 
above  in  PI.  XIV.  figs.  1,  In,  16;  Lower  Chalk, 
Southeram  Pit,  Lewes.  The  head  is  shown  to  have  been 
long  and  laterally  compressed,  with  a  very  acute  snout ; 
but  the  cranium  is  crushed  downwards  in  the  fossil  and 
broken  in  a  sharp  transverse  fracture  at  about  its  middle. 
The  frontal  bones  (/r.)  are  very  extensive,  almost  reaching 
the  occipital  border;  and  their  inner  half  is  remarkably 
smooth,  marked  only  by  radiating  lines  of  growth.  Im¬ 
mediately  behind  them  the  stout  supraoccipital  bone 
(s.occ.)  is  seen,  distinctly  separating  the  parietals,  but 
not  exhibiting  any  median  crest  or  keel.  The  bones  of 
the  cheek  are  almost  completely  destroyed,  but  the  cha¬ 
racteristic  anterior  portion  of  the  premaxilla  (pmx.)  is 
indicated  by  fragments  on  both  sides.  On  the  right 
(fig.  1)  the  remains  of  this  bone  exhibit  traces  of  the  two 
enlarged  teeth  (i,  ii),  and  on  both  sides  it  is  partly 
broken  away  to  expose  the  middle  enlarged  teeth  of  the 
lower  jaw.  On  the  left  (fig.  1  a)  an  undetermined 
fragment  of  bone  (a?.)  overlaps  the  anterior  end  of  the 
premaxilla,  but  this  probably  has  no  connection  wdth  the 
jaws.  The  mandibular  ramus  is  best  displayed  on  the 
right,  but  its  anterior  pointed  end  is  much  broken  here 
and  the  dentition  is  more  completely  displayed  on  the 
left.  The  ramus  is  deepest  at  the  hinder  end,  where  the 
dentary  (cZ.)  is  seen  to  extend  in  a  narrow  band  above 
the  comparatively  small  articulo-angular  bone  (ar/.)  ;  it 


262

exhibits  a  characteristic  gentle  curvature,  with  the  con¬ 
cavity  upwards  ;  and  its  outer  face  is  remarkably  convex 
and  smooth,  with  an  incurved  lower  border.  Of  the  two 
enlarged  mandibular  teeth,  one  occurs  on  the  right,  but 
both  are  preserved  on  the  left ;  they  are  slightly  recurved, 
apparently  compressed  to  a  sharper  edge  in  front  than 
behind,  and  the  basal  part  of  the  outer  face  is  marked  by 
very  delicate  vertical  striations.  Six  similar,  but  relatively 
small  and  short  teeth,  are  preserved  posteriorly  on  the 
right,  while  four  remain  on  the  left ;  of  those  on  the 
right,  the  hindermost  is  the  largest.  Another  similar 
though  small  tooth  is  seen  just  in  front  of  the  enlarged 
teeth  on  the  left,  and  between  this  and  the  anterior  end 
of  the  jaw  there  is  a  diminishing  series  of  recurved 
denticles.  At  the  hinder  end  of  the  right  cheek  part 
of  the  quadrate  bone  {qu.)  is  exposed  ;  and  immediately 
behind  this  there  is  the  much-thickened  anterior  border 
of  the  preoperculum  Q:>.op.).  Caqqron  Coll,

the  natural  size  from  both  sides  and  above  in  PI.  XIY. 
figs,  2,  2a,  2  6;  English  Chalk.  The  very  narrow 
cranium,  sharply  compressed  above  the  otic  region,  is 
indicated  as  before ;  and  the  remarkably  acute  snout  is 
especially  well  shown.  On  both  sides  there  are  remains 
of  extensive  though  delicate  postorbital  cheek-plates  (5.0.); 
and  the  anterior  attenuated  ends  of  the  characteristic 
premaxillae  {pinx.)  are  displayed  apposed  to  the  slender 
ethmoidal  region  and  apparently  just  meeting  in  front. 
The  two  enlarged  premaxillary  teeth  are  partly  shown  on 
both  sides  (i,  ii),  but  the  second  on  the  left  seems  to  be 
a  little  displaced  through  fracture.  The  smooth,  delicate 
mandible  is  much  broken  ;  but  the  extent  of  the  small 
articulo-angular  element  {ag.')  is  seen  especially  on  the 
right,  and  there  are  remains  of  the  characteristic  small 
teeth  on  both  sides.  Enniskillen  Coll,

portion  of  the  premaxilla  is  shown  from  the  outer  aspect

P.  5666.  Imperfect  rostrum,  split  longitudinally,  showing  the 
anterior  portions  of  the  premaxillac  apposed  to  the  slender 
ethmoidal  region  ;  probably  from  Lower  Chalk,  Cuxton, 
Kent.  On  the  left  side  the  anterior  part  of  the  pre¬ 
maxilla  is  proved  to  be  solid,  while  its  flattened  oral 
border,  to  which  the  bases  of  the  two  enlarged  teeth  still 
remain  fixed,  is  flanked  by  a  slight  rim  or  outer  wall. 
The  hinder  part  of  the  bone,  which  is  somewhat  bent 
dowmwards  upon  the  anterior  part  immediately  behind  the 
second  enlarged  tooth,  consists  only  of  the  thin,  deepened 
outer  wall  with  the  tooth-bearing  border  fixed  on  its  inner 
face  like  a  shelf ;  the  fragment  preserved  bears  two  teeth 
of  considerable  size.  The  two  enlarged  teeth  of  the  right 
premaxilla  are  entirely  broken  away,  but  immediately  in 
front  of  the  attachment  of  the  second  there  are  remains  of 
two  very  small  teeth  on  the  outer  margin.  There  are  also 
indications  of  the  two  posterior  teeth  already  mentioned 
on  the  left.  Harford  Coll. 

P.  5673.  Hinder  end  of  jaws  of  left  side  ;  probably  from  Low^er 
Chalk,  Cuxton.  The  quadrate  is  shown,  meeting  the 
hyomandibular  at  its  postero-superior  angle  hut  in 
contact  with  the  almost  reniform  metapterygoid  along  its 
upper  border.  The  hinder  end  of  the  premaxilla  is  im¬ 
perfect,  but  still  retains  two  typical  teeth  and  the  base  of 
a  third.  The  shape  of  the  hinder  end  of  the  mandible 
resembles  that  on  the  right  side  of  the  type  specimen  ;  but 
the  articulo-angular  element  is  less  exposed  on  the  outer 
face  than  in  the  latter,  where  the  dentary  seems  to  have 
been  partly  flaked  away.  Harford  Coll.

Type.  Head  and  abdominal  region  ;  olini  Amic  Collection,  Paris. 

The  type  species,  attaining  a  length  of  about  0'2.  Length  of  the 
head  with  opercular  apparatus  equalling  or  slightly  exceeding  the 
length  of  the  trunk  from  the  pectoral  arch  to  the  base  of  the  caudal 
fin  ;  maximum  depth  of  trunk  contained  from  four  to  five  times  in 
the  same  measurement.  Dorsal  fin  arising  at  the  middle  point 
between  the  occiput  and  the  base  of  the  caudal  fin  ;  pelvic  fins  about 
half  as  large  as  the  pectorals  and  arising  just  in  advance  of  the 
origin  of  the  dorsal ;  anal  fin  completely  behind  the  dorsal,  arising 
behind  the  middle  point  between  the  pelvic  pair  and  the  caudal  fin. 
Scales  of  the  lateral  line  conspicuously  thicker  than  the  others.

Type.  Imperfect  fish ;  British  Museum. 

A  large  form  apparently  closely  resembling  the  type  species,  but 

the  trunk  perhaps  more  slender  and  the  hinder  teeth  of  the  pre¬ 
maxilla  relatively  larger. 

Form.  Log.  Upper  Cretacnous  :  Sahel  Alma,  Mt.  Lebanon. 

P.  4851.  The  type  specimen  about  0*4  in  length,  described  and 
figured  loc.  cit.  The  skull  is  crushed  so  that  the  right 
and  left  sides  of  the  jaws  are  separated.  The  produced 
upper  jaw  is  thus  proved  to  consist  only  of  the  elongated 
premaxillae,  while  the  mandible  is  shown  to  be  destitute 
of  a  presymphysial  bone.  The  premaxilla  bears  a  spaced 
series  of  large,  slender,  conical  teeth,  which  are  erect, 
gradually  increase  in  size  backwards,  and  are  shown  by 
fragments  to  have  been  very  large  on  that  part  of  the 
bone  which  is  in  contact  with  the  cranial  rostrum. 
Between  the  large  teeth  there  are  smaller  denticles.  The 
spaced  teeth  of  the  dentary  are  much  smaller  than  those 
of  the  premaxilla,  and  seem  to  attain  their  greatest  size  in 
the  middle  of  the  bone,  diminishing  both  backwards  and 
forwards.  The  structure  of  the  hinder  part  of  the  jaws  is 
not  clear,  but  the  mandible  does  not  seem  to  have  been

elevated  in  the  coronoid  region,  and  its  articulation  is 
almost  as  far  back  as  the  occiput.  There  seem  to  be 
remains  of  cheek-plates.  The  vertebral  column  of  a 
swalloTved  fish  can  be  distinguished  in  the  abdominal 
region.  The  fins  are  too  imperfect  to  admit  of  counting 
their  ravs.  Leivis  Coll.

49526.  Imperfect  specimen  exhibiting  the  head  and  the  greater 
part  of  the  trunk,  noticed  by  Davis,  loc.cit.  p.  615.  Some 
of  the  anterior  neural  spines  are  laminar  expansions, 
obliquely  truncated  above,  tapering  to  a  point  below. 
The  imperfect  dorsal  fin  has  12  supports.  The  course  of 
the  lateral  line  is  indicated  by  a  thickening  of  the  scales.

A  species  as  large  as  the  type,  but  with  shorter  vertebrae  and

apparatus  considerably  exceeding  the  length  of  the  trunk  from  the 
pectoral  arch  to  the  base  of  the  caudal  fin  ;  maximum  depth  of 
trunk  contained  about  three  times  in  the  same  measurement.  Eins

mentary  specimen  of  Scombroclupea  macrophtlialma,  now  in  the 
Edinburgh  Museum  of  Science  and  Art. 

The  name  Rliinellus  nasalls  was  given  by  Agassiz  (lYeues  Jahrb. 
1835,  p.  291)  to  an  indeterminable  fish  from  the  Upper  Eocene  of 
Monte  Bolca,  described  and  figured  as  Pegasus  lesiniformis  by  G.  S. 
Yolta,  Ittiolit.  Y^eronese  (1796),  p.  clix,  pi.  xxxix.  fig.  1. 

The  name  Rliinellus  schilli  was  given  by  H.  von  Meyer  (iYeues 
Jahrb.  1863,  p.  450)  to  some  undetermined  fragments,  not  of  this 
genus,  from  the  Lower  Tertiary  of  Hammerstein,  Baden.

Family  GONORHYNCHID^. 

Trunk  fusiform  or  elongated,  and  caudal  region  relatively  short. 
Supraoccipital  bone  not  prominent,  but  extending  forwards  to  the 
frontals  and  separating  the  parietals  in  the  median  line  ;  squamosal 
suturally  united  with  parietals  and  completely  covering  the  otic 
bones  except  behind;  snout  not  produced;  cueek-plates  rudimentary. 
Mandibular  suspensorium  much  inclined  forwards,  and  gape  of 
mouth  small ;  premaxilla  smaller  than  maxilla,  but  excluding 
latter  from  the  oral  margin  ;  teeth,  if  present,  chiefly  or  exclusively 
on  some  inner  bones  of  mouth.  Opercular  apparatus  complete, 
with  few  bran chiostegal  rays  and  no  gular  plate.  Vertebral  centra 
well  ossified,  but  usually  pierced  by  notochord  ;  abdominal  vertebras 
with  robust  transverse  processes  bearing  delicate  ribs,  which  do 
not  completely  encircle  the  abdominal  cavity  ;  a  compound  hypural 
bone  at  the  base  of  the  tail.  Intermuscular  bones  present.  Fin- 
fulcra  absent;  pectoral  arch  without  precoracoid  process;  dorsal  and 
anal  fins  small ;  no  adipose  dorsal  fin.  Scales  narrow  and  elongated, 
very  deeply  imbricated,  and  often  extending  over  the  cheeks  and 
opercular  apparatus. 

The  only  known  existing  species  of  this  family  is  Gonorhynchus 
gt'eyi^  which  inhabits  the  seas  off  Japan,  South  Africa,  Australia, 
and  Yew  Zealand.  Its  gill-cleft  is  narrow,  and  pseudobranchiae  are 
present ;  there  is  no  air-bladder  ;  the  stomach  is  simple,  without 
blind  sac,  while  the  pyloric  appendages  occur  in  small  number.

Teeth  apparently  wanting  on  the  margin  of  the  jaws;  but  stout 
and  blunt  conical  teeth  present  on  some  of  the  inner  bones  of  the 
mouth,  probably  on  the  pterygoids  and  hyoid  apparatus;  upper 
branchiostegai  rays  comparatively  broad.  Vertebrae  approximately 
50  in  number,  35  being  abdominal  and  the  remainder  caudal ;  ribs 
short  and  delicate.  Paired  fins  relatively  large,  the  pectorals  not 
much  exceeding  the  pelvic  pair  in  size,  the  latter  remote  and 
opposed  to  the  origin  or  anterior  part  of  the  dorsal,  which  is  scarcely 
if  at  all  behind  the  middle  of  the  back ;  dorsal  and  anal  fins  each 
with  from  7  to  12  rays  ;  caudal  fin  slightly  forked.  Scales  distinctly 
elongated  [but  their  hinder  margin  not  yet  observed] ;  no  scales 
extending  over  the  head  ;  strong  fulcral  scales  on  the  borders  of  the 
caudal  pedicle  at  the  base  of  the  caudal  fin.

P.  9173.  Type  specimen,  shown  of  the  natural  size  iu  PI.  XV.  fig.  3. 

The  crushed  remains  of  the  head  are  exposed  partly  from 
the  right  side,  partly  from  below.  The  cranium  seems  to 
he  exposed  from  beneath,  and  displays  the  attenuated 
form  of  the  elongated  rostrum.  Beneath  its  anterior 
extremity  there  lies  a  stout  cuxwed  bone  {mx.)  shaped 
much  like  the  maxilla  of  Gonorhynclius  ;  while  just  behind 
this  there  appears  to  be  the  anterior  pointed  end  of  the 
toothless  dentary  (cZ.).  Still  further  back  there  are 
remains  of  large  bluntly-conical  teeth,  some  apparently 
belonging  to  the  upper  jaw,  but  the  largest  (Z.)  occurring 
just  above  the  ceratohyal  as  if  they  had  been  fixed  upon 
the  hyoid  arch.  All  the  vertebral  centra  are  longer  than 
deep  and  much  constricted ;  while  fractured  examples, 
both  in  the  abdominal  and  caudal  regions,  seem  to  indicate 
that  a  delicate  strand  of  the  notochord  penetrated  each  of 
them.  The  ribs  are  shown  to  be  short  and  slender,  not 
reaching  the  ventral  border  of  the  fish  ;  the  neural  and 
haemal  spines  in  the  caudal  region  are  straight,  much 
inclined  backwards,  and  comparatively  stout,  while  there 
seems  to  have  been  scarcely  any  fusion  or  expansion  of 
the  haemals  supporting  the  caudal  fin.  The  fins  are 
closely  adpressed  to  the  trunk,  so  that  at  first  sight  they 
are  not  conspicuous.  The  remarkably  elongated  rays  of 
the  paired  fins,  however,  are  well  preserved ;  and  the 
arrangement  of  the  fins  is  clearly  as  stated  in  the  specific 
diagnosis.  The  caudal  fin  is  shown  to  be  cleft.  The 
scales  are  antero-posteriorly  elongated  and  striated,  but 
their  crushed  remains  are  too  much  confused  to  permit 
the  determination  of  their  precise  shape  and  characters. 
Stout  styliform  fulcral  ridge-scales  occur  on  each  border 
of  the  caudal  pedicle  at  the  origin  of  the  caudal  fin.

spines  of  the  abdominal  region  bear  a  laminar  expansion,

49528.  Specimen  figured  by  Davis,  loc.  cit.  pi.  xxvi.  fig.  3.  The 
cranium  is  shown  to  be  long  and  narrow,  and  the  quad¬ 
rate  can  be  distinguished  beneath  it,  the  articulation  for 
the  mandible  probably  being  below  the  anterior  margin 
of  the  orbit.  The  mouth  is  opened,  and  a  long  and  slender, 
gently  arched  bone  in  front  may  be  the  premaxilla.  Both 
rami  of  the  mandible  are  imperfectly  preserved ;  but  there 
are  no  traces  of  teeth.  The  branchiostegal  rays  are 
relatively  large  and  scattered,  but  12  can  be  counted, 
proving  that  there  must  have  been  at  least  6  pairs.  The 
clavicle  is  relatively  small,  though  in  the  published  figure 
detached  bones  below  it  are  made  to  appear  continuous 
with  it.  One  of  the  pectoral  fins  is  seen  on  the  flank,  and 
its  single  elongated  ray  is  distinctly  observable  curving 
downwards,  bifurcating  at  the  distal  end.  Both  pelvic 
fins  are  well  preserved,  but  not  spreading ;  and  the 
characteristic  dorsal  and  anal  fins  are  depressed.

49530.  Specimen  figured  by  Davis,  loc.  cit.  pi.  xxvi.  fig.  4.  The 
mandible  is  sufiiciently  well  preserved  to  indicate  the 
relatively  small  size  of  the  terminal  mouth :  and  below 
the  head  there  are  remains  of  the  large  branchiostegal 
rays.  The  number  of  vertebrse  is  shown  to  be  about  50, 
and  the  short  ribs  are  covered  by  one  of  the  pelvic  fins. 
One  of  the  small  pectoral  fins  is  seen  at  the  lower  border 
of  the  trunk  immediately  behind  the  branchiostegal  rays. 
It  is  imperfect  distally,  but  clearly  exhibits  12  delicate 
rays.  The  pelvic  fins  are  crushed  as  usual,  so  that  one  is 
above  the  other,  the  lowermost  spreading  and  displaying 
17  rays,  the  uppermost  closed.  The  dorsal  fin  seems  to 
comprise  about  16  rays,  and  some  of  its  expanded  trian¬ 
gular  supports  are  well  shown.  It  is  difficult  to  determine 
whether  or  not  delicate  scales  were  present.  Certain 
brownish  markings,  especially  in  the  abdominal  region.

Family  ESOCID^. 

Supraoccipital  bone  extending  forwards  to  the  frontals  and 
separating  the  parietals  in  the  median  line  ;  otic  region  prominent 
and  squamosal  reduced.  Mandibular  suspensorium  inclined  forwards, 
but  gape  large  and  dentition  powerful ;  symplectic  bone  present ; 
premaxiUge  relatively  small  and  separated  by  the  ethmoidal 
rostrum ;  maxiUa  forming  the  greater  part  of  the  upper-^ border 
of  the  mouth.  Opercular  apparatus  complete,  with  12,  to  20 
branchiostegal  rays  and  no  gular  plate ;  gill- opening  very  wide. 
Abdominal  vertebrae  without  transverse  processes  ;  ribs  not  com¬ 
pletely  encircling  abdominal  cavity.  Intermuscular  bones  present.

A  species  attaining  a  length  of  about  0’7.  Head  -with  opercular 
apparatus  occupying  nearly  one  third  of  the  total  length  to  the 
base  of  the  caudal  fin.  Dorsal  and  anal  fins  each  comprising  about 
15  divided  and  articulated  rays  preceded  by  3  or  4  short  undivided 
rays.  Pelvic  fins  nearer  to  the  anal  than  in  E.  Jucius,  and  scales 
considerably  larger  than  in  the  latter  species. 

It  is  difiicult  to  count  the  fin-rays  owing  to  imperfections  and 
displacement  of  their  right  and  left  halves  during  fossilisation,  but 
the  formula  given  for  the  dorsal  and  anal  is  approximately  correct.

raoiitli ;  teeth  on  premaxilla  and  dentary,  none  on  palate,  except 
very  rarely  on  vomer.  Opercular  apparatus  complete,  with  few 
(4  to  6)  .  branchiostegal  raj-s  and  no  gular  plate.  Abdominal 
vertebrae. with  transverse  processes  ;  ribs  stout  and  long.  Pectoral 
arch  without  precoracoid  process.  A  single  dorsal  fin,  more  or 
less  remote,  without  adipose  dorsal.  Trunk  covered  with  scales, 
which  extend  more  or  less  over  the  head. 

The  existing  Cyprinodonts  are  small  fishes  ranging  throughout 
the  temperate  and  tropical  regions,  except  Australasia,  the  majority 
confined  to  freshwaters,  but  a  few  found  in  brackish  water  and  on 
the  sea-coast.^  Only  one  extinct  genus  is  known  with  certainty, 
while  a  second  is  recognised  provisionally. 

Genus  PROLBBIAS^  Sauvage. 

[Bull.  Soc.  Hist.  Nat.  Toulouse,  vol.  viii.  1874,  p.  187.] 

Trunk  regularly  fusiform,  laterally  compressed  ;  caudal  pedicle 
deep.  Head  very  small,  with  obtuse  snout ;  cleft  of  mouth 
relatively  small ;  premaxillse  not  produced  forwards,  and  probably 
not  protractile ;  teeth  simply  conical,  apparently  arranged  in  a 
single  series.  Transverse  processes  of  abdominal  vertebrae  very 
short.  Pelvic  fins  present  but  relatively  small ;  dorsal  and  anal 
fins  small,  not  much  extended,  directly  opposed  in  the  hinder  half 
of  the  fish  ;  anal  fin  never  modified  ;  caudal  fin  truncated  or  some¬ 
what  forked.  Scales  large,  ornamented  with  fine  parallel  striations 
and  pectinations.  The  two  sexes  apparentl}"  similar. 

This  genus  seems  to  be  most  closely  related  to  the  existing 
Liicania,  Girard,  of  North  America,  and  Fiindulus^  Lacepede,  which 
has  a  still  more  extensive  range  in  North  America  besides  being 
abundant  in  tropical  Africa  and  southern*’ Europe.  *'  -  *•

the  oesophagus  by  a  duct  in  the  adult  (physostomous) ;  optic  nerves 
decussating ;  intestine  without  spiral  valve  ;  reproductive  organs 
with  efferent  ducts. 


Synopsis  of  Families. 

Preinaxilla  and  maxilla  usually  entering  the 
upper  border  of  the  mouth  ;  teeth  usually 
on  margin  of  jaws,  and  lower  pharyngeals 
not  falciform  ;  symplectic  bone  present ;  no 
barbels ;  adipose  dorsal  fin  usually  present ; 

scales,  but  no  bony  scutes .  Chaeacinid^  (p.  297). 

Premaxilla  excluding  maxilla  from  upper  border 
of  mouth  ;  jaws  toothless,  but  lower  phar¬ 
yngeals  falciform  and  strongly  toothed ; 
symplectic  bone  present ;  barbels  frequent ; 
no  adipose  dorsal  fin ;  scales,  but  no  bony 
scutes  .  Cyprixid^  (p.  299). 

Preraaxilla  almost  alwavs  excluding:  maxilla 
from  upper  border  of  mouth ;  den^lition 
very  variable,  but  lower  pharyngeals  rarely 
falciform :  no  symplectic  bone ;  barbels 
present;  adipose  dorsal  fin  usually  pre¬ 
sent  ;  no  scales,  but  often  bony  scutes  ....  Silueid.®  (p.  324). 


Family  CHARACINID^. 

Supraoccipital  bone  prominent,  but  not  completely  separating  the 
well-developed  parietals  in  the  median  line ;  squamosal  suturally 
united  with  parietals  and  completely  covering  the  otic  bones  except 
behind ;  cheek-plates  usually  well  developed.  Symplectic  bone 
present ;  premaxilla  small  and  maxilla  relatively  large,  both  entering 
the  upper  border  of  the  mouth ;  teeth  variable,  more  or  less  acu¬ 
minate,  chiefly  on  the  premaxilla,  maxilla,  and  dentary  bones;  lower 
pharyngeals  not  falciform.  No  barbels.  Opercular  apparatus  com¬ 
plete,  but  few  branchiostegal  rays.  Pectoral  arch  with  separate 
supraclavicle ;  a  single  dorsal  fin  usually  followed  by  a  small 
adipose  dorsal  on  the  tail.  Trunk  covered  with  scales,  but  no  bony 
scutes. 

No  extinct  genera  of  this  family  are  known  with  certainty.  Th  e 
existing  forms  are  distributed  in  the  freshwaters  of  tropical 
America  and  Africa,  attaining  their  maximum  development  in 
South  America,  where  there  are  no  C5"prinoids. 

The  structure  of  the  Characinoid  skull  is  described  by  M.  Sage- 
mehl,  Morphol.  Jahrb.  vol.  x.  (1885),  pp.  1-119,  pis.  i.,  ii.

Type.  Imperfect  fish  ;  oliin  Lavater  Coll.,  Zurich. 

A  species  attaining  a  length  of  about  0*18.  Length  of  head  with 
opercular  apparatus  somewhat  less  than  the  maximum  depth  of  the 
trunk,  which  is  contained  three  times  or  slightly  more  in  the  total 
length  to  the  base  of  the  caudal  fin.  Yertebrse  18  or  19  in  the 
abdominal,  16  in  the  caudal  region  ;  13  pairs  of  ribs,  the  hinder- 
most  comparatively  small.  Pelvic  fins,  with  about  9  rays,  arising 
slightly  in  advance  of  the  dorsal,  which  also  comprises  9  rays,  the 
foremost  being  a  short  spine,  the  second  articulated,  the  others 
both  articulated  and  divided  distally ;  anal  fin  with  12  rays,  like 
those  of  dorsal ;  caudal  fin  moderately  forked. 

The  differences  in  proportions  noted  by  xlgassiz  between  L.  oenin¬ 
gensis  and  the  so-called  L.  latiuscidus  seem  to  be  due  to  accidental 
distortion  ;  while  the  absence  of  the  small  hindermost  pair  of  ribs 
in  the  former  probably  results  from  defective  preservation.

The  three  existing  species  Leuciscus  rutilus  (Linn.),  L.  erythroph- 
ihalmus  (Linn.),  and  L.  cephalus  (Linn.),  seem  to  be  represented  by 
pharyngeal  teeth  in  the  RorescBed  Series  of  Horfolk  (E.  T.  Hewton, 
Vert.  Rorest  Bed  [Mem.  Geol.  Surv.  1882],  pp.  124-126,  pi.  xviii.

Several  imperfect  fishes,  apparently  not  Cyprinoids,  from  a  marine

The  so-called  Leucisciis  dorsalis,  L.  dumerili,  and  L.  sicamis,  with 
two  supposed  new  species,  L.  cecconii  and  L.  saiivagei,  are  also 
described  from  an  Upper  Miocene  Tripoli  at  Mondaino,  Province  of 
Forli,  Italy;  but  the  original  specimens  appear  to  be  as  unsatis¬ 
factory  as  those  from  Licata  (I.  Bonomi,  Bivista  Ital.  Paleont. 
vol.  ii.  1896,  pp.  227-232,  pi.  v.  figs.  1,  8).  Two  specimens  of  this 
nature  in  the  Collection  are  numbered  P.  5548-49.

Bheinl.  vol.  xi.  1854,  p.  11  (as  sub-genus  of  Leucisciis). 

Skeleton  very  robust  and  mouth  anterior.  Pharyngeal  teeth 
cuneiform,  slightly  hooked  at  one  end,  in  a  single  series.  A  pair  of 
barbels  at  the  angle  of  the  mouth.  Pseudobranchiae  rudimentary. 
Pelvic  fins  with  foremost  ray  much  thickened  and  expanded,  closely 
articulated  but  not  subdivided;  dorsal  fin  short,  in  middle  of  back, 
without  bony  spine  ;  anal  fin  short,  behind  the  dorsal ;  caudal  fin 
sub  truncated  or  moderately  forked ;  all  fins  enveloped  in  rather 
thick  skin.  Scales  small,  elongated  and  imbricating,  imbedded  in 
thick,  mucus-secreting  skin  ;  lateral  line  complete,  low  on  the  flank, 
extending  along  the  middle  of  the  side  of  the  tail. 

An  exclusively  European  genus,  the  existing  species  found  princi¬ 
pally  among  the  weeds  and  mud  of  still  freshwaters.

total  length  to  the  base  of  the  caudal  fin.  About  36  vertebrse,  half 
being  caudal.  Pelvic  fins  arising  opposite  the  origin  of  the  dorsal, 
which  is  nearly  as  deep  as  the  trunk  at  its  insertion  and  comprises 
10  rays,  the  foremost  being  a  short  spine,  the  second  articulated, 
the  others  both  articulated  and  divided  distally ;  anal  fin  with  9  or

behind  the  pelvic  pair  :  anal  fin  short ;  caudal  fin  rounded,  truncate, 
or  slightly  forked.  Scales  minute. 

Existing  species  occur  only  in  the  freshwaters  of  Europe  and  Asia. 
It  is  impossible  with  certainty  to  separate  the  extinct  species  here 
recorded  from  the  genus  Kemachilus,  Cuvier  (which  has  no  erectile

SupraocciiDital  bone  prominent ;  otic  region  com2)letely  roofed  by 
membrane-bones  ;  brain-case  produced  forwards  between  the  orbits  : 
cheek-plates  much  reduced.  Symplectic  bone  absent ;  prem axilla 
extended,  almost  always  excluding  the  maxilla  from  the  upper  border 
of  the  mouth  ;  teeth  very  variable  ;  lower  pharyngeals  rarely  falci¬

usually  absent,  and  branchiostegal  rays  few  or  wanting.  Pectoral 
arch  without  distinct  supraclavicle  :  a  single  dorsal  fin  often  followed 
by  an  adipose  dorsal  on  the  tail.  Trunk  without  scales,  but  often 
more  or  less  armoured  with  bonv  scutes. 

The  existing  members  of  this  family  are  distributed  in  the  fresh- 
waters  of  all  temperate  and  tropical  regions,  and  a  few  are  littoral

Head  depressed  and  bones  of  cranial  roof  ornamented  and  exposed, 
or  covered  only  with  very  thin  skin  ;  a  small  vacuity  in  the  supra - 
occipital  and  frontal  bones.  Eyes  small ;  cleft  of  mouth  transverse, 
terminal,  of  moderate  width;  teeth  on  dentary,  premaxilla,  and 
vomer.  Pectoral  fins  with  robust  spine,  often  serrated  on  the 
anterior  border  ;  pelvic  fins  with  six  rays ;  dorsal  fin  without  spine, 
much  extended  and  occupying  nearly  the  whole  of  the  back  ;  no 
adipose  dorsal:  anal  fin  much  extended;  caudal  fin  rounded.  Skin 
naked.

ser.  X.  vol.  iii.  p.  248,  pi.  xxxvi.  fig.  4. 

Type.  Nearly  complete  skull ;  British  Museum. 

A  species  probably  about  0'4  in  length,  known  only  by  the  skull, 
which  is  provisionally  ascribed  to  Heterobranchus  on  account  of 
its  close  resemblance  to  the  skull  of  H.  interynedius^  and  also  on 
account  of  the  long  backward  extension  of  its  supraoccipital  bone. 
Not  yet  precisely  definable,  but  differing  from  H.  intermedins  in  its 
relatively  shorter  and  wider  frontal  vacuity  and  its  ethmoid  much 
narrowed  in  front. 

Form.  ^  Log.  Lower  Pliocene :  Siwalik  Hills,  India.

Genus  SILURUS^  Linnaeus. 

[Syst.  Nat.  ed.  10,  1758,  p.  304.] 

Head  not  much  depressed,  the  lateral  muscles  extending  some¬ 
what  forwards  over  the  cranial  roof,  and  the  whole  covered  ^vith 
the  soft  skin.  Gape  of  mouth  extending  to  beneath  the  orbit ; 
teeth  very  minute,  villiform,  present  on  the  premaxillae  and  dentaries, 
also  on  the  vomer  but  not  on  the  palatines.  Pectoral  fin  with 
robust  spine,  serrated  on  the  posterior  or  both  borders ;  pelvic  fins 
with  more  than  eight  rays,  arising  behind  the  dorsal  fin,  which  is 
short-based  and  without  anterior  spine ;  no  adipose  dorsal ;  anal  fin 
much  extended,  almost  or  completely  united  with  the  caudal,  which 
is  rounded.  Skin  naked. 

The  surviving  species  of  this  genus  inhabit  the  freshwaters  of

Genus  RHINEASTES,  Cope. 

[Proc.  Amer.  Phil.  Soc.  vol.  xii.  1872,  p.  486.] 


An  imperfectly  known  genus  related  either  to  Pimelodus  or  ^  to 
Arius.  Head  depressed  and  bones  of  cranial  roof  marked  with 
conspicuous  rugosity ;  frontal  fontanelle  closed,  hut  marked  by  a 
smooth  deep  groove.  Teeth  minute  and  villiform,  extending  over 
vomer.  Pectoral  fin  with  robust  spine,  serrated  on  one  or  both 
borders ;  a  nuchal  shield  between  the  supraoccipital  and  the  spine 
of  the  dorsal  fin. 

In  the  typical  species,  R.  peltatus,  the  nuchal  shield  is  large  and 
massive  ;  in  the  other  Eocene  species  (forming  sub-genus  Astephus, 
Cope)  it  is  narrow  and  short. 

The  genus  is  known  only  by  fragments  from  the  Lower  Tertiary

Genus  BUCKLANDIUM,  Kdnig. 

[leones  Foss.  Sect.  1825,  p.  4.] 

A  genus  known  only  by  the  imperfect  skull  and  pectoral  arch, 
which  closely  resemble  the  corresponding  parts  of  the  existing 
Auchenoglanis  ^  of  the  Nile  and  West  African  rivers.  Distinguished 
from  the  latter  by  the  complete  fusion  of  the  cranial  roof-bones, 
the  larger  orbit  and  frontal  fontanelle,  and  the  relatively  larger 
pectoral  arch,  which  does  not  taper  below.  Head  laterally  com¬ 
pressed,  with  rounded  tuberculated  roof,  evidently  not  covered  with

ACTINOPTERYGIT. 


Suborder  YI.  APODES. 

Notochord  more  or  less  persistent,  but  the  vertebral  centra 
always  complete  constricted  cylinders,  none  coalesced  ;  tail  tapering, 
usually  without  expanded  or  fused  neural  or  haemal  supports  at  the 
extremity.  Symplectic  bone  absent ;  mandible  simple,  each  ramus 
consisting  only  of  two  elements  (dentary  and  articulo-angular). 
Pectoral  arch  not  suspended  from  cranium ;  precoracoid  arch 
absent ;  infraclavicular  plates  absent ;  pectoral  fin  with  more  than 
five  basals.  Pelvic  fins  absent.  Scales  rudimentary  or  absent. 
In  the  living  forms — air-bladder,  when  present,  connected  with  the 
oesophagus  by  a  duct  in  the  adult  (physostomous),  optic  nerves 
decussating,  intestine  without  spiral  valve,  and  reproductive  organs 
without  efierent  ducts. 


Family  MUR.^NID^E. 

Trunk  much  elongated,  the  caudal  region  being  relatively  very 
long.  Parietal  bones  large  and  meeting  in  a  median  suture ; 
squamosal  suturally  united  with  parietals  and  covering  the  greater 
part  of  the  otic  region.  Premaxillse  small  and  fused  with  the 
ethmoidal  rostrum  ;  maxilla  well-developed,  forming  most  of  the 
upper  border  of  the  mouth  ;  pterygo-palatine  arcade  much  reduced 
or  rudimentary.  Branchial  and  opercular  apparatus  usually  more 
or  less  reduced;  generally  a  few  delicate  branchiostegal  rays. 
Vertebrae  very  numerous,  those  of  the  abdominal  region  with  short 
and  broad  transverse  processes,  small  and  delicate  ribs,  and  very 
short  neural  spines.  Intermuscular  bones  present.  Fin-fulcra 
absent ;  fin-rays  articulated  and  divided  distally ;  dorsal  and  anal 
fins  excessively  extended,  and  a  separate  caudal  fin  almost  always 
absent. 

The  extinct  species  of  this  family  are  too  imperfectly  known  to 
be  generically  determined  with  certainty.  It  is  evident,  however, 
that  they  represent  some  of  the  more  generalised  types ;  and  the 
Cretaceous  genus  mentioned  below  is  unique  in  retaining  a  normal 
caudal  fin. 

A  figure  of  the  skeleton  of  Anguilla  is  published  by  Agassiz,

Teeth  small,  bluntly  conical,  and  arranged  in  numerous  series. 
Slender  branchiostegal  rays  not  curving  round  the  opercular 
apparatus.  Yertebrae  somewhat  exceeding  100  in  number,  the 
hindermost  bearing  a  pair  of  expanded  hypural  bones.  Pectoral 
fins  present;  dorsal  fin  arising  immediately  behind  the  occiput  and 
extending  to  the  caudal  fin,  which  has  stouter  rays  and  is  very 
small  but  separate.  Scales  rudimentary.

The  type  species,  attaining  a  length  of  about  0*3.  Length  of 
head  with  opercular  apparatus  contained  about  six  times  in  the 
total  length  to  the  base  of  the  caudal  fin  ;  anal  fin  considerably 
more  than  twice  as  long  as  the  portion  of  trunk  in  front  of  it. 
Anterior  neural  arches  much  expanded,  their  appended  spines 
apparently  small  and  low.

P.  4860.  Type  specimen,  shown  of  the  natural  size  in  PI.  XYIII. 

fig.  I.  A  few  of  the  blunt  teeth  are  seen  among  the 
fractured  remains  of  the  cranium ;  while  below  it  the 
extent  of  the  mandible  can  be  distinguished.  The 
branchial  region  is  probably  shortened  by  crushing,  and 
remains  of  the  very  slender  branchiostegal  rays  lie  across 
fragments  of  the  branchial  arches  and  the  rather  stout 
clavicle.  The  vertebrae  cannot  be  readily  counted,  but 
there  seem  to  be  about  35  in  front  of  the  origin  of  the 
anal  fin,  and  not  less  than  73  beyond.  The  neural 
arches  in  the  abdominal  region  are  very  stout  laminae, 
but  their  spines  are  not  seen.  The  transverse  processes 
and  very  short  slender  ribs  are  distinct.  The  long 
slender  neural  and  haemal  spines  in  the  caudal  region  are 
also  conspicuous.  The  pectoral  fins  are  not  preserved. 
The  dorsal  fin  clearly  arises  directly  above  the  pectoral 
arch,  extending  continuously  along  the  back  to  the  caudal 
extremity,  while  the  remarkably  extended  anal  fin  is 
continued  equally  far  backwards.  There  are  distinct 
indications  of  two  expanded  hypural  bones  at  the  tip  of

the  tail,  saggestive  of  a  separate  caudal  fin,  of  which  a 
few  rays  remain.  The  characteristic  intermuscular  bones 
are  exhibited  dorsally  throughout  the  trunk,  and  below 
the  vertebral  axis  in  the  caudal  region.  The  limestone 
is  stained  by  the  fossil,  but  there  are  no  traces  of 
scales.  Lewis  Coll. 

P.  4751.  Larger  but  more  imperfect  and  distorted  specimen,  dis¬ 
playing  parts  of  the  head,  pectoral  arch,  pectoral  fin,  and 
scales  (PI.  XYIII.  fig.  2).  The  stout  supraoccipital  bone 
of  the  skull  (s.occ.)  projects  considerably  backwards,  and 
the  rostrum  is  slender.  The  length  of  the  cranium, 
indeed,  appears  to  be  more  than  three  times  as  great  as 
its  width  at  the  occiput.  The  right  mandibular  ramus  is 
shown  {md.),  rising  to  a  low  coronoid  process  immediately 
behind  its  toothed  portion.  The  clustered  teeth  are  very 
stout  and  blunt.  The  vertebrae  behind  the  head  are 
exposed  from  above,  but  the  neural  spines  are  broken 
away  from  the  much  expanded  arches.  There  are  im¬ 
pressions  of  some  of  the  short  ribs  ;  while  a  few  of  the 
pointed  transverse  processes  are  preserved  in  the  hinder 
part  of  the  abdominal  region.  The  tail  is  much  distorted 
and  too  imperfect  for  description.  The  clavicles  (cl.)  are 
seen  immediately  behind  the  head,  one  of  them  displaying 
its  slender,  arched  form,  with  tapering  upper  end.  One 
of  the  pectoral  fins  {pet.)  is  also  preserved,  though  a  little 
distorted  and  imperfect  distally.  Behind  this,  the  brownish 
impression  of  the  soft  parts  of  the  fish  is  curiously 
mottled,  as  if  there  were  indications  of  small,  rudimentary 
quadrangular  scales.  Further  back,  the  course  of  part 
of  the  intestine  is  marked  by  its  phosphatic  contents.

An  imperfectly  known  species,  represented  only  by  small  speci¬ 
mens  not  exceeding  0-1  in  length.  Length  of  head  with  opercular 
apparatus  contained  about  seven  times  in  the  total  length  to  the 
base  of  the  caudal  fin  ;  anal  fin  less  than  twice  as  long  as  the  portion 
of  trunk  in  front  of  it. 

A  specimen  of  this  fish  in  the  Museum  of  the  Syrian  Protestant 
College,  Beyrout,  displays  the  caudal  fin  very  clearly. 

Form.  Loc.  Upper  Cretaceous :  Hakel,  Mount  Lebanon. 

P.  4372.  Type  specimen,  shown  of  the  natural  size  in  PI.  XYIII. 

fig.  3.  The  remains  of  the  head  are  very  imperfect,  but 
present  no  features  at  variance  with  the  interpretation  of 
the  afiinities  of  the  fish  here  suggested.  The  opercular 
apparatus  is  wide  in  proportion  to  its  depth,  and  there 
seems  to  be  a  suboperculum  between  the  operculum  and 
the  very  slender  branchiostegal  rays.  The  latter  are  long, 
but  not  curved  upwards  behind.  The  two  sigmoidally 
bent  clavicles,  with  pointed  ends,  are  partly  shown  ;  and 
there  are  traces  of  the  scapular  arch  supporting  a  delicate 
pectoral  fin.  The  vertebral  column  is  imperfectly  pre¬ 
served,  but  throughout  its  length  the  expanded  neural 
arches  are  shown  to  be  relatively  large.  There  are 
impressions  of  short,  slender  ribs  in  the  abdominal  region, 
while  the  neural  and  haemal  spines  are  stouter,  though 
still  slender  in  the  caudal  region.  The  rays  of  the  dorsal 
and  anal  fins  are  very  fine  and  difficult  to  observe.  The 
former  seems  to  extend  along  the  whole  length  of  the 
back,  but  in  the  abdominal  region  it  is-  imperfectly  pre¬ 
served  and  crushed  downwards  upon  the  vertebral 
column.  So  far  as  preserved,  the  anal  does  not  attain 
much  more  than  half  the  extent  of  the  dorsal  fin.  The 
imperfectly  preserved  caudal  fin  is  clearly  separate,  and 
is  formed  of  somewhat  stouter  rays  supported  by  ex¬ 
panded  hmmal  spines.  Lewis  Coll.

[Bull.  Soc.  Beige  Geol.  vol.  x.  1898,  Mem.  p.  239.] 

A  genus  founded  on  an  imperfect  cranium,  which  most  closely^ 
resembles  that  of  the  existing  Myrus,  but  differs  from  the  latter  in 
exhibiting  a  relatively  larger  basisphenoid  and  a  larger  anterior 
extension  of  the  squamosal.  Teeth  on  vomer  and  premaxillary 
region  relatively  large. 

If  the  second  and  third  extinct  species  mentioned  below  are 
correctly  referred  to  this  genus,  its  diagnosis  may  be  extended 
thus: — Teeth  bluntly  conical.  Yertebrse  somewhat  exceeding  100 
in  number.  Pectoral  fins  small;  dorsal  fin  arising  above  the 
pectoral  arch  and  continuous  with  the  anal  round  the  pointed

long  as  the  abdominal  region.  Anterior  neural  spines  in  form  of 
Tery  broad  laminae. 

This  species  is  described  by  Agassiz  as  most  closely  related  to  the 
existing  Myrus  vulgaris,  Kaup  {Murmna  myrus,  Linn.),  of  the 
Mediterranean. 

Form.  4*  Loc.  Upper  Eocene:  X.  Italy. 

P.9427.  Imperfect  specimen  wanting  extremity  of  tail;  Monte 
Bolca,  near  Yerona.  The  maximum  width  of  the  cranium 
is  shown  to  equal  one  third  of  its  length,  and  the  slightly 
expanded  end  of  the  slender  rostrum  is  less  elongated 
than  in  E.  dolloi.  The  teeth,  so  far  as  preserved,  are 
very  stout  and  bluntly  conical.  The  maxillae  are  robust. 
The  branchiostegal  rays  are  not  less  than  15  in  number, 
and  do  not  curve  upwards  at  their  hinder  end.  The 
neural  canal  of  the  vertebral  axis  is  seen  to  be  very 
laj.g0^  History  unJcnoum.

more  imperfect  than  in  the  previous  specimen,  but  similar 
branchiostegal  rays  are  preserved.  Bemains  of  one  of  the 
small  pectoral  fins  occur  ;  and  the  dorsal  fin  is  observed 
to  arise  directly  above  this  fin.  The  hinder  halt  of  the

[Syst.  Nat.  ed.  10,  1758,  p.  297.] 

Trunk  elongate-fusiform;  the  slender  caudal  pedicle  without 
median  lateral  keel.  Teeth  small  and  conical,  on  margin  of  jaws, 
vomer,  and  palatines ;  gill-rakers  long,  slender,  and  numerous. 
Vertebrae  about  14  in  the  abdominal,  16  or  17  in  the  caudal  region  ; 
the  centra  much  constricted,  but  without  lateral  pits  ;  all  haemal 
arches  simple.  Pectoral  and  pelvic  fins  small  ;  dorsal  fins  widely 
separated,  the  anterior  consisting  of  9  to  12  spines  simply  articulated 
with  their  supports;  posterior  dorsal  and  anal  fins  small,  similar, 
and  opposite,  followed  by  5  to  9  detached  finlets ;  caudal  fin  deeply 
forked.  Scales  very  small,  uniformly  covering  the  trunk,  scarcely 
if  at  all  enlarged  in  the  pectoral  region. 

Recent  species  are  very  widely  distributed  in  temperate  and 
tropical  seas.

Type.  Distorted  fish  ;  Geological  Museum,  Zurich. 

The  type  species,  attaining  a  length  of  about  0*4.  Proportions 
uncertain,  but  length  of  head  with  opercular  apparatus  equalling 
about  half  that  of  the  vertebral  column.  Vertebrae  16  in  the 
abdominal,  22  in  the  caudal  region.  Pectoral  fins,  when  adpressed, 
reaching  the  beginning  of  the  caudal  region ;  anterior  dorsal  fin 
consisting  of  10  spines  ;  posterior  dorsal  and  anal  fins  with  about 
20  articulated  rays,  of  which  an  uncertain  number  are  detached 
finlets. 

Nearly  all  the  known  specimens  of  this  species  are  much  distorted, 
and  it  seems  probable  that  Wettstein  is  correct  in  proposing  the 
synonymy  given  above.

Genus  SCOMBRINUS,  novum. 

[ex  Agassiz  MS.,  Pep.  Brit.  Assoc.  1844  (1845),  p.  308.] 

An  imperfectly  known  genus  founded  on  the  skull,  which  is- 
essentially  identical  with  that  of  Scomber,  but  with  larger  teeth. 
Erontal  bones  flattened  and  rugose,  the  flattened  area  tapering 
backwards  mesially  to  a  point  meeting  the  crest  of  the  supraoccipital ; 
fossae  for  lateral  muscles  of  trunk  not  extending  forwards  much 
beyond  the  hinder  margin  of  the  frontals.  Teeth  on  margin  of 
jaws  rather  large,  stout,  conical,  and  well-spaced,  not  much  laterally 
compressed.  Scales  small  and  smooth,  not  much  enlarged  in  the 
pectoral  region.

ossified ;  cleft  of  mouth  extending  as  far  as  or  beneath  the  anterior 
half  of  the  orbit ;  premaxilla  very  stout,  deepest  in  front,  and  its 
slightly  convex  oral  margin  bearing  a  single  close  series  of  minute 
conical  teeth  ;  mandible  short  and  deep,  the  backwardly  ascending 
oral  margin  of  the  dentary  with  a  similar  regular  series  of  slightly 
larger  teeth ;  preoperculum  forming  a  great  triangular  expansion, 
and  suboperculum  relatively  deep.  Vertebral  centra  much  con¬ 
stricted  and  strengthened  on  the  middle  of  each  side  by  a  sharp 
ridge.  Pectoral  fins  arising  near  the  ventral  border  ;  pelvic  fins 
more  remote  than  the  anterior  part  of  the  dorsal,  each  comprising 
7  or  8  rays  ;  dorsal  fin  imperfectly  known,  but  its  anterior  portion 
apparently  consisting  of  about  8  spines  in  which  the  right  and  left 
halves  are  not  fused  together,  its  posterior  portion  of  articulated 
and  divided  rays  ;  anal  fin  comparatively  small,  partly  or  completely 
behind  the  dorsal ;  caudal  fin  deeply  forked,  with  slender  lobes  and 
their  outermost  rays  exhibiting  numerous  closely  arranged  oblique 
articular  lines,  which  are  very  finely  jagged.  Scales  large,  very 
deeply  overlapping,  smooth,  and  not  serrated  or  crenulated  on  the 
posterior  margin.  Lateral  line  conspicuous,  a  simple  tube  piercing 
all  the  scales  it  traverses,  arising  low  down  on  the  fiank  not  far 
above  the  pectoral  fin. 

~  This  definition  is  based  on  the  specimens  enumerated  below.  x4n 
examination  of  the  original  specimen  in  the  Geneva  Museum,  on 
which  the  genus  was  founded,  leaves  many  essential  features  in  the 
structure  of  the  fish  doubtful.  The  large  bone  at  the  margin  of  the 
upper  jaw  appears,  at  first  sight,  to  be  a  Clupeoid  maxilla  ;  but  a 
consideration  of  the  new  specimens  now  described  suggests  that  it 
is  a  premaxilla  most  closely  resembling  that  of  the  Atherinidae. 
The  dorsal  fin  in  the  type  specimen  is  much  more  imperfect  than 
is  indicated  in  Pictet’s  rather  diagrammatic  figure,  only  a  few  frag¬ 
ments  remaining.  Two  pelvic  fin-rays  in  the  same  specimen  seem 
to  be  displaced  backwards  ;  and  the  anal  fin  evidently  comprises 
the  series  of  comparatively  small  and  delicate  rays  observed  between 
these  and  the  caudal  fin.

siderably  expanded  at  the  angle  and  is  shown  to  have 
been  marked  with  delicate  radiating  grooves.  The  origin 
of  the  dorsal  fin  is  indicated  by  remains  of  a  few  spinous 
rays.  The  course  of  the  lateral  line,  low  on  the  flank

Type.  Head  and  abdominal  region  ;  British  Museum. 

A  large  and  robust  species,  attaining  a  length  of  about  0-45. 
Length  of  head  with  opercular  apparatus  scarcely  exceeding  the 
maximum  depth  of  the  trunk  and  contained  slightly  more  than 
four  times  in  the  total  length  to  the  base  of  the  caudal  fin.  A 
narrow  border  of  very  fine  granulations  immediately  above  the 
teeth  on  the  outer  face  of  the  premaxilla ;  anterior  margin  of 
prebperculum  much  thickened,  especially  at  the  angle,  from  which 
numerous  undulations,  almost  ridges,  radiate ;  operculum  smooth. 
Pectoral  fins  long  and  narrow,  with  about  14  rays  ;  pelvic  fins  with 
8  rays,  the  foremost  stoutest,  arising  much  nearer  to  the  caudal 
than  to  the  pectoral  fins  ;  a»terior  dorsal,  with  not  less  than  8  rays, 
arising  at  a  distance  from  the  occiput  equal  to  the  total  length  of 
the  skull.  ^ About  eight  or  ten  transverse  series  of  scales  in  advance 
of  the  anterior  dorsal  fin,  each  with  approximately  twelve  scales  on 
either  side  ;  the  scales  when  abraded  exhibiting  traces  of  very  fine 
parallel  or  slightly  radiating  lines  directed  antero-posteriorly  in 
the  exposed  area.

constricted  cylinders,  apparently  pierced  originally  by  the 
notochord :  they  are  strengthened  by  slight  longitudinal 
ridges  only  in  the  caudal  region.  The  ribs  are  short, 
straight,  and  delicate.  The  short  neural  spines  in  the 
abdominal  region  are  thickened,  those  near  the  occiput 
being  small  expanded  laminae.  The  pectoral  fin  has  an

characters  noted  in  the  previous  specimens ;  Puy-de- 
Dome.  Egerton  Coll, 

P,  387  Two  imperfect  specimens  ;  St.  Saturnin,  near  St.  Amand- 
Tallende.  The  cranium  is  partly  exposed  from  above, 
showincr  the  much-constricted  interorbital  region  and  the 
gently  rounded  roof  of  the  brain-case.  Enniskillen  Coll. 

P.  5946.  Large  imperfect  specimen  ;  St.  Saturnin. 

Purchased,  1889. 

The  following  specimen  may  perhaps  represent  a  member  of  the 
family  Ammodytidse,  but  it  is  too  imperfect  for  satisfactoigy^ 
determination  : — 

46540.  Imperfect  caudal  region  0’065  in  length,  associated  with  a 
specimen  of  Rhinellus-,  Upper  Cretaceous,  Sahel  Alma, 
Mount  Lebanon.  The  vertebral  centra  are  too  imperfect 
for  recognition,  but  there  are  about  24  in  the  caudal 
region  ;  the  neural  and  haemal  arches  are  short.  The 
dorsal  fin  is  extended,  probably  with  about  20  rays ;  the 
anal  fin,  with  14  rays,  is  opposed  to  the  hinder  half  of 
the  latter.  The  caudal  fin  is  incomplete  distally.  The 
scales  are  indistinct.  ,  Lewis  Coll. 

Family  SCOMBRESOCID.^. 

Maxilla  enteritig  the  border  of  the  upper  jaw  ;  dentition  feeble; 
opercular  apparatus  complete,  with  few  branchiostegal  rays,  and 
the  gill-opening  wide.  Lower  pharyngeal  bones  united.  Yertebrae 
nunaerous,  from  45  to  85  in  the  total  length ;  centra  of  abdominal 
vertebrse  with  transverse  processes  for  the  support  of  slender  ribs. 
Pelvic  fins  without  spine  but  with  only  about  6  divided  rays  ;  one 
remote  dorsal  fin,  without  an  anterior  spinous  portion;  anal  fin 
opposed  to  the  posterior  dorsal.  Scales  in  regular  series,  but 
usually  a  keel  along  each  side  of  the  lower  region  of  the  body. 

Nearly  all  the  existing  Scombresocidee  are  marine,  only  a  few 
small  forms  living  in  freshwater  in  the  tropics.  No  extinct  genus 
is  known.

not  more  remote  than  the  anterior  dorsal  fin  ;  posterior  dorsal  and 
anal  fins  nearly  similar  and  opposed  ;  a  series  of  free  fin-supports 
between  the  two  dorsal  fins ;  caudal  fin  deeply  forked.  Scales 
large,  very  deeply  overlapping,  smooth,  and  not  serrated,  rarely 
crenulated  on  the  posterior  margin  ;  some  extending  over  the

Yertebrse  from  45  to  50  in  number.  Pelvic  fins  arising  much 
nearer  to  the  pectorals  than  to  the  anal  and  far  in  advance  of  the 
anterior  dorsal,  which  seems  to  comprise  only  four  or  five  spinous 
rays  and  is  almost  as  far  from  the  occiput  as  from  the  tail.  The 
distance  between  the  origin  of  the  two  dorsal  fins  somewhat  less 
than  that  between  the  origin  of  the  posterior  dorsal  and  the  caudal 
fin  ;  anal  fin  arising  somewhat  in  advance  of  the  posterior  dorsal.

The  undefined  name  Atherina  minidissima  was  also  given  by 
Agassiz  (Poiss.  Poss.  vol.  iv.  1835,  p.  43)  to  a  fish  from  Monte 
Bolca. 

Genas  RHAMPHOGIMATHUS,  Agassiz. 

[Poiss.  Poss.  vol.  V.  pt.  i.  1844,  pp.  9,  104.] 

Syn.  Mesogaster,  L.  Agassiz,  ibid.  pp.  9,  105. 

As  Atherina.,  but  snout  elongated  to  an  acute  point  and  scales 
relatively  smaller. 

In  the  present  state  of  knowledge  it  is  impossible  to  distinguish 
this  fish  satisfactorily  from  the  existing  Atherine  genera  named 
Chirostoma  (Swainson,  1839),  Menidia  (Bonaparte,  1840),  Ather- 
inoides  (Bleeker,  1853),  Atherinichthys  (Bleeker,  1853),  Basilichthys 
(Girard,  1854),  Atherinopsis  (Girard,  1854),  Labidesthes  (Cope, 
1870),  (Steindachner,  1875),  and  Leurestlies  (Jordan  & 

Gilbert,  1880).  Opinions  vary  as  to  how  many  of  these  are 
synonymous.

Type.  Imperfect  fish  ;  Paris  Museum  of  Natural  History. 

The  type  species  of  the  so-called  genus  Mesogaster,  attaining  a 
length  of  about  0*2.  Length  of  head  with  opercular  apparatus 
contained  about  three  and  a  half  times,  and  maximum  depth  of 
trunk  about  seven  times  in  the  total  length  of  the  fish.  Premaxillary 
border  apparently  straight  and  teeth  very  minute.  Vertebrae  about 
18  in  the  abdominal,  22  in  the  caudal  region.  Pelvic  fins  arising 
somewhat  nearer  to  the  pectorals  than  to  the  anal.  Anterior 
dorsal  fin,  with  six  slender  spinous  rays  and  the  third  the  longest, 
arising  opposite  a  point  just  behind  the  pelvic  pair;  space  between 
the  two  dorsal  fins  about  equal  to  that  between  the  origin  of  the 
posterior  dorsal  and  the  caudal,  and  this  space  exhibiting  a  series 
of  ten  free  fin-supports ;  posterior  dorsal  and  anal  fins  equal  and 
directly  opposed,  each  with  nine  or  ten  rays,  the  foremost  being  a 
short  spine. 

Form.  Log.  Upper  Eocene  :  Monte  Bolca,  near  Verona. 

P.  5128.  Fine  specimen  about  0’2  in  length,  showing  all  the 
generic  and  specific  characters  mentioned  above  except 
the  minute  teeth.  The  straight  cleft  of  the  mouth  clearly 
extends  as  far  as  the  orbit.  Bemains  of  a  small  un¬ 
digested  fish  are  observed  in  the  abdomen.

1885,  p.  247,  pi.  xxii.  fig.  2),  from  the  Upper  Cretaceous  of  West¬ 
phalia,  does  not  belong  to  this  genus  or  even  to  the  Atherinidie. 
The  type  specimen,  in  the  Academy  of  Miinster,  is  too  imperfect 
for  exact  determination  but  seems  to  be  a  Scopeloid  fish. 


Family  AIUGILID.F]. 

Trunk  more  or  less  elongate  and  laterally  compressed.  Pre¬ 
maxilla  excluding  maxilla  from  border  of  upper  jaw  ;  mandible  not 
prominent  and  cleft  of  mouth  small,  with  dentition  feeble  or  absent ; 
opercular  apparatus  complete,  with  about  five  branchiostegal  rays, 
and  the  gill-opening  wide.  Lower  pharyngeal  bones  separate. 
Yertebrse  few,  not  more  than  24  to  26  in  number ;  centra  of 
abdominal  vertebrae  with  transverse  processes  for  support  of  ribs. 
Pelvic  fins  with  one  spine  and  five  divided  rays,  abdominal,  but  the 
pelvic  bones  in  contact  with  the  postclavicle  ;  two  dorsal  fins,  the 
anterior  spinous  and  with  very  few  rays ;  anal  fin  opposed  to  the 
posterior  dorsal.  Scales  in  regular  series,  large  or  of  moderate  size. 

In  the  existing  fauna,  these  are  fishes  with  a  protractile  mouth 
feeding  chiefly  on  organic  substances  or  small  animals  mixed 
"  with  mud  or  sand.  The  organs  of  the  pharynx  are  accordingly 
modified  into  a  filtering  apparatus.  The  various  genera,  with 
numerous  species,  now  inhabit  the  coasts  and  freshwaters  of  all  the 
temperate  and  tropical  regions.  The  only  known  extinct  species 
seem  to  belong  to  the  surviving  genus  Miigil, 


Genus  MUGIL,  Linnseus. 

[Syst.  hTat.  ed.  10,  1758,  p.  316.] 

Snout  short  and  obtuse,  and  the  cleft  of  the  mouth  not  reaching 
the  orbit ;  no  true  teeth  in  the  mouth,  but  a  calcified  setiform 
fringe  on  the  border  of  both  jaws  ;  anterior  extremity  of  mandible 
acute  ;  antorbital  cheek-plate  serrated  ;  eleven  or  twelve  abdominal 
and  thirteen  or  twelve  caudal  vertebrae ;  the  abdominal  vertebrae 
with  strong,  broad  transverse  processes,  while  several  of  the  anterior 
neural  spines  are  expanded  into  short  and  broad  laminae,  sometimes 
partly  confluent.  Pelvic  fins  inserted  in  advance  of  anterior  dorsal 
fin  ;  anterior  dorsal  comprising  four  spines  ;  posterior  dorsal  and 
anal  nearly  similar  and  opposed  ;  caudal  fin  forked.  Scales  of 
moderate  size,  smooth  and  very  rarely  crenulated  or  serrated;  some

fish.  Poremost  spine  of  anterior  dorsal  fin  much,  stouter  and  larger 
than  the  others  ;  distance  between  the  origin  of  this  and  the  posterior 
dorsal  fin  greater  than  that  between  it  and  the  occiput,  about  equal 
to  the  distance  between  the  origin  of  the  posterior  dorsal  and  the 
caudal ;  posterior  dorsal  relatively  small,  with  one  spine  and  seven 
articulated  rays anal  much  larger  than  the  posterior  dorsal,  about 
half  in  advance  of  the  latter,  exhibiting  apparently  three  spines  and 
eight  or  nine  articulated  rays.

in  parts  by  transverse  fractures.  An  im  pression  of  part 
of  the  frontal  "region  bears  traces  of  minute  tubercles 
arranged,  along  the  radiating  lines  of  growth.  The  oper¬ 
culum  is  quite  smooth.  The  vertebral  centra  are  delicate 
much-constricted  cylinders,  apparently  pierced  by  a 
persistent  thread  of  notochord ;  and  large  transverse 
processes  bearing  the  ribs  are  conspicuous  in  the  anterior 
portion  of  the  abdominal  region.  Long,  very  slender 
intermuscular  bones  are  also  seen.  The  neural  and 
haemal  spines  in  the  caudal  region  are  very  short,  broad, 
and  recumbent.  The  pelvic  fin-suppor/:s  are  expanded 
laminae,  and  the  anterior  pelvic  fin-spine  is  nearly  as  long 
and  stout  as  the  foremost  divided  ray,  which  seems  to  be 
followed  by  five  others.  Of  the  dorsal  fin,  only  a  fragment 
is  distinguishable  opposite  to  the  anal.  Tne  diminutive 
anal  fin-spine  is  borne  by  a  considerably  expanded 
support ;  while  the  length  of  the  foremost  divided  anal 
ray  probably  exceeds  the  depth  of  the  trunk  at  its  inser¬ 
tion.  The  imperfect  caudal  fin,  consisting  of  very  broad 
rays,  seems  to  have  been  forked.  A  series  of  enlarged 
dermal  scutes  is  only  preserved  between  the  pelvic  and 
dorsal  fins  on  one  side ;  but  the  whole  of  the  trunk  is 
covered  by  very  small,  rounded  or  rhomboidal  scutes  of 
uniform  size,  which  do  not  appear  to  have  been  in 
contact.  Parchased,  1862.

elongated  median  rays.  Scales  absent,  but  a  series  of  rudimentary 
bony  scutes  along  the  lateral  line  and  the  median  dorsal  line. 

Existing  species  occur  on  the  shores  of  the  Indian  Ocean  and  of 
the  tropical  region  of  the  Atlantic  Ocean.

Family  CEXTRISCID.E. 

Trunk  laterally  compressed,  and  irregularly  oblong  or  deepened ; 
snout  much  produced  into  a  tube,  and  small  toothless  mouth 
terminal.  Gills  pectinated;  opercular  apparatus  complete.  Some 
anterior  vertebrae  usually  elongated,  those  of  the  abdominal  region 
and  some  anterior  caudals  "with  large  transverse  processes.  Pelvic 
fins  'without  spine  but  with  5  or  6  divided  rays ;  an  enlarged  spine 
and  usually  other  small  spines  in  front  of  the  dorsal  fin ;  anal  fin 
without  anterior  spine,  opposed  to  the  soft  dorsal ;  caudal  fin 
distinct.  Skin  with  a  partial  bony  armour  and  also  with  small 
scales. 

These  are  small  marine  fishes,  very  widely  distributed. 

Synopsis  of  Genera. 

Caudal  region  relatively  large  ;  few  dorsal  spines, 
the  second  excessively  enlarged;  pelvic  fins 
considerably  behind  pectorals  ;  bony  plates 
dorsallv  and  ventrallv  and  flanks  covered 

vuth  small  scales .  Centriscus  (Eecent). 

Caudal  region  relatively  large ;  pelvic  fins  partly 
beneath  pectorals ;  bony  plates  dorsally,  not 
ventrally,  but  flanks  covered  with  small 

scales .  E7iamp)}iosu§  (p.  377). 

Caudal  region  relatively  very  small ;  pelvic  fins 
reduced,  considerably  behind  pectorals  ;  dorsal 
and  ventral  bony  dermal  armour  extensive, 
but  no  scales  .  Ampliisile  (p.  378). 

Isolated  spines  from  the  Lower  Pliocene  of  Orciano,  Tuscany,  are 
ascribed  to  Centriscus  under  the  name  of  C.  toni  by  It.  Lawley, 
Isuovi  Studi  Pesci,  etc.,  Colline  Toscane  (1876),  p.  79. 

Genus  RHAMPHOSUS,  Agassiz. 

[Poiss.  Foss.  vol.  iv.  1844,  p.  270.]

Type.  Imperfect  fish  ;  Museum  of  Natural  History,  Paris. 

The  type  species,  attaining  a  length  of  about  0*12.  Proportions 
somewhat  uncertain  owing  to  imperfection  of  few  known  specimens  ; 
but  snout  extremely  attenuated,  the  length  of  the  head  with  oper¬ 
cular  apparatus  probably  equalling  that  of  the  trunk  from  the 
pectoral  arch  to  the  base  of  the  caudal  fin,  also  about  equalling  the 
length  of  the  dorsal  fin-spine,  which  bears  posterior  denticulations. 
Probably  8  abdominal  vertebrae,  and  14  caudals.  Dorsal  and  anal  fins 
equal  and  directly  opposed,  each  with  9  rays.  Scales  very  minute.

Genus  AMPHISIUB  (Klein),  Cuvier. 

[Begne  Animal,  vol.  ii.  1817,  p.  350.] 

Trunk  oblong  and  much  laterally  compressed,  with  very  small 
caudal  region  curved  downwards.  About  6  large  and  elongated 
abdominal  vertebrae,  14  very  small  caudals.  Pelvic  fins  rudi¬ 
mentary,  well  behind  the  pectorals  ;  caudal  fin  rounded.  Bony 
plates  dorsally  and  ventrally  in  abdominal  region,  the  dorsal  armour 
intimatelv  connected  with  the  endoskeleton  ;  no  scales.

Trunk  much  elongated,  not  dilated.  Pectoral  fins  present ; 
dorsal  fin  small  and  very  remote;  caudal  fin  small,  truncated 
behind.  Dermal  armour  apparently  incomplete,  perhaps  wanting

Type.  Imperfect  distorted  fish ;  Palaeontological  Museum, Munich. 

The  type  species,  imperfectly  known  by  two  distorted  specimens 
about  0’06  in  length.  Maximum  depth  of  trunk  less  than  its 
length  from  the  pectoral  arch  to  the  base  of  the  caudal  fin,  and 
about  three  times  as  great  as  the  width  of  the  caudal  pedicle. 
Dorsal  fin  with  5  spines  and  10  divided  rays,  the  distance  between 
its  hinder  end  and  the  caudal  fin  equal  to  the  length  of  its  own 
base-line ;  anal  fin  with  3  or  4  spines  and  10  divided  rays,  arising 
opposite  the  middle  of  the  dorsal  fin,  and  the  length  of  its  base-line 
nearly  equal  to  that  of  the  latter  fin. 

W.  von  der  Marck  considers  that  the  scales  are  enlarged  along 
the  course  of  the  lateral  line.  He  also  regards  the  second  and 
larger  specimen,  provisionally  ascribed  by  Agassiz  to  this  species,  as 
truly  representing  a  distinct  form.  He  erroneously  applies  the 
name  A.  parvus  to  the  latter.

T^pe.  Nearly  complete  fish;  British  Museum. 

A  species  attaining  a  length  of  about  0*12.  Length  of  head  with 
opercular  apparatus  somewhat  exceeding  the  depth  of  the  abdominal 
region  below  the  vertebral  column.  Maximum  depth  of  trunk  con¬

very  slender,  its  width  scarcely  exceeding  one  quarter  of  the 
maximum  depth.  Dorsal  fin  with  5  longitudinally  ribbed  spines 
and  about  18  divided  rays,  arising  approximately  at  the  middle 
point  between  the  end  of  the  snout  and  the  base  of  the  caudal  fin  ; 
anal  fin  much  less  extended,  with  a  rudimentary  spine  at  the

origin,  3  longitudinally  ribbed  spines  and  14  divided  rays,  arising 
opposite  the  middle  of  the  dorsal  fin. 

A  careful  study  of  the  specimens  enumerated  below  suggests  that 
the  supposed  differences  between  the  various  named  forms  here 
included  inP.  rmseggeri  are  due  to  imperfections  in  the  preservation 
of  the  specimens.  The  shape  of  the  fish  and  the  arrangement  of  its 
dorsal  and  anal  fins  conduce  to  very  variable  distortion ;  while  the 
longitudinal  ribbing  of  the  fin-spines  frequently  affords  a  false 
impression  of  their  number.

A  deep-bodied  species,  about  as  large  as  the  type.  Length  of

vol.  ii.  1857,  p.  103,  pi.  i.  lig.  2),  is  referable  to  Pycnosterinx 
discoides.  According  to  P.  Bassani  (communicated  MS.),  the

The  dorsal  fin  comprises  5  spines  and  about  23  divided  rays,  the 
anal  fin  2  or  3  spines  and  about  18  rays.  The  scales  are  too

A  species  attaining  a  length  of  about  0*3.  Length  of  head  with 
opercular  apparatus  considerably  less  than  the  maximum  depth  of 
the  trunk,  which  nearly  equals  the  length  from  the  hinder  margin 
of  the  clavicle  to  the  base  of  the  caudal  fin.  Dorsal  fin  occupying 
nearly  one  half  of  the  back,  comprising  6  very  stout,  longitudinally 
ribbed  spines  and  8  to  10  divided  rays,  the  length  of  the  longest 
spine  almost  equalling  one  third  the  depth  of  the  trunk  at  its 
insertion ;  anal  fin  with  7  or  8  divided  rays  preceded  by  3  or  4 
very  stout  spines,  which  gradually  increase  to  a  length  about 
equalling  that  of  the  longest  dorsal.  Scales  very  finely  and 
delicately  pectinated ;  the  lateral  line  traversing  about  the  ninth 
longitudinal  series  from  the  ventral  border. 

In  the  fossils  from  the  English  Chalk  recorded  below,  the  super¬ 
ficial  layer  of  the  external  bones  and  scales  is  frequently  destroyed, 
at  least  in  part,  producing  an  accidental  smoothness.

ornamented  with  tuberculated  ridges  on  its  outer  face, 
and  is  excavated  in  front  as  if  for  the  reception  of  a 
smaller  anterior  supramaxilla.  The  dentary  (d.')  bears 
numerous,  clustered,  minute  blunt  teeth,  like  those  of  the 
premaxilla ;  its  outer  face  is  deeply  channelled  below  for 
the  slime-canal,  and  the  longitudinal  ridge  above  the

channel  is  tuherculated.  The  angular  {ag.)  has  a  similar 
conformation,  but  its  tuherculated  ridge  is  widened  into  an 
extensive  radiately- ornamented  area.  The  preoperculum 
(p.o^.)  also  exhibits  a  deep  groove  for  the  slime-canal, 
and  is  not  much  expanded  at  the  angle.  The  other 
opercular  bones  display  their  characteristic  rugose  orna¬ 
ment.  The  deep  and  narrow  operculum  (op.)  is  produced 
into  two  short  and  broad  spines  at  its  hinder  margin,  the 
upper  being  connected  by  a  strong  ridge  with  the  point  of 
suspension.  The  suboperculum  (.s.op.)  is  relatively  small, 
with  a  large  anterior  ascending  process.  The  inter¬ 
operculum  (i.op.)  is  of  remarkable  extent.  The  upper 
expanded  portion  of  the  clavicle  is  more  finely  and  closely 
ornamented  than  the  opercular  apparatus.  The  large  and 
deep  anterior  scales  are  broken  and  displaced.

A  species  attaining  a  length  of  about  0*15.  Length  of  head  with 
opercular  apparatus  about  equal  to  the  maximum  depth  of  the 
trunk  and  contained  one  and  a  half  times  in  the  length  from  the 
pectoral  arch  to  the  base  of  the  caudal  fin.  Opercular  apparatus 
conspicuously  ornamented  with  irregular  ridges  and  tubercles  ; 
preopercular  spine  very  short ;  upper  opercular  spine  large  and 
broad,  lower  spine  comparatively  insignificant.  Dorsal  fin  with  11 
ribbed  spines  and  11  or  12  divided  rays,  the  latter  portion  com¬ 
paratively  deep  but  less  than  half  as  much  extended  as  the  former 
portion ;  anal  fin  with  4  ribbed  spines  and  8  or  9  divided  rays,  the 
fourth  spine  very  slender,  the  stout  third  spine  only  feebly  ribbed 
and  as  long  as  the  longest  dorsal  spines,  of  which  the  length 
scarcely  equals  half  the  depth  of  the  trunk  at  their  insertion. 
Scales  very  delicately  serrated.

ACTING  PTERYQII, 


Family  APHREDODERID^. 

American  freshwater  fishes,  essentially  similar  to  the  Berycidae, 
hut  with  premaxillae  not  protractile,  no  distinct  lateral  line,  and  the 
vent  very  far  forward.  Each  pelvic  bone  forked. 

No  extinct  members  of  this  family  are  represented  in  the  Collection, 
hut  the  following  genera  and  species  have  been  described  from 
American  freshwater  formations  :  —

Family  CYTTID^. 

Head  without  superficial  cavities  for  mucus ;  premaxillae  pro¬ 
tractile,  and  dentition  feeble.  Branchiostegal  rays  7  or  8  in 
number.  Vertebrae  about  30  in  number ;  the  posterior  abdominal 
centra  with  downwardly  bent  transverse  processes.  Pelvic  fins  with 
one  spine  and  more  than  five  articulated  rays  ;  dorsal  and  anal  fins 
extended,  the  former  at  least  with  anterior  spines,  which  are  not 
so  numerous  as  the  articulated  rays.  Squamation  either  irregular, 
very  fine,  or  absent,  often  comprising  only  a  few  scutes  ;  lateral  line 
inconspicuous. 

There  do  not  appear  to  be  any  fossils  in  the  Collection  referable 
to  this  family. 

A  distorted  fish,  with  incomplete  pelvic  fins,  too  imperfect  for

and  the  head  is  clearly  covered  with  scales.  The  vertebrae 
are  distinctly  12  in  the  abdominal,  18  in  the  caudal  region  ^ 
the  ribs  are  stout,  not  reaching  the  ventral  border.  There 
are  fragments  of  the  paired  fins,  and  the  characteristic

The  type  species,  attaining  a  length  of  about  0'25.  Length  of 
head  with  opercular  apparatus  considerably  exceeding  half  the 
maximum  depth  of  the  trunk,  and  the  latter  measure  nearly 
equalling  the  length  from  the  pectoral  arch  to  the  base  of  the  caudal 
fill.  Pelvic  fins  comprising  a  relatively  short  spine,  one  simple  ray 
closely  articulated  distally,  and  four  rays  both  articulated  and 
divided  distally ;  dorsal  fin  arising  in  advance  of  the  anal  but 
extending  as  far  backwards  as  the  latter  to  the  base  of  the  short 
caudal  pedicle ;  dorsal  fin  with  seven  stout,  sharply-ridged  spines, 
the  seventh  about  two  thirds  as  long  as  the  next  ray,  which  is  the 
longest,  simple  but  closely  articulated  distally,  and  followed  by  from 
22  to  26  gradually  shortening  rays,  both  divided  and  articulated 
distally;  anal  fin  much  less  elevated  than  the  dorsal,  with  four 
similar  spines,  one  simple  articulated  ray,  and  from  18  to  22  divided 
rays.  Scales  very  finely  and  uniformly  granulated  and  serrated. 

The  difiPerences  between  the  two  forms  distinguished  by  W.  von 
der  Marck  seem  to  be  due  entirely  to  accidents  in  preservation.

P.  4743.  Type  specimen,  very  imperfectly  figured  by  Davis  loo.  cit. 

and  erroneously  ascribed  by  him  to  the  so-called  Plataos 
minor.  The  sharply-pointed  supraoccipital  crest  is  con¬ 
spicuous,  and  the  comparatively  small  eye  is  indicated 
by  a  black  stain.  The  cleft  of  the  mouth  is  shown  to  be 
very  oblique,  and  the  maxilla  is  clearly  expanded  behind. 
Ten  branchiostegal  rays  are  preserved  in  position  below  the 
smooth  opercular  apparatus.  10  abdominal  and  14  caudal 
vertebrae  can  be  counted.  The  pectoral  fin  is  small,  com¬ 
posed  of  very  delicate  rays  ;  a  long,  slender  postclavicle 
extends  backwards  and  downwards  beneath  it  to  the 
ventral  border.  The  comparatively  stout  rays  of  the 
pelvic  fins  are  adpressed  to  the  ventral  border  and  overlap 
the  anal  spines.  Four  or  five  anterior  articulated  rays  of 
the  dorsal  fin  are  excessively  elongated,  forming  a  peak 
in  the  front  part  of  the  fin,  which  rapidly  becomes  quite 
low  in  its  hinder  half.  The  low  anal  fin,  with  at  least  3 
gradually  lengthening  stout  spines  and  18  articulated  rays, 
extends  backwards  for  the  length  of  two  vertebrae  behind 
the  dorsal  fin.  The  middle  rays  of  the  caudal  fin  are  very 
short  and  rather  sparse ;  this  fin  being  deeply  forked 
and  with  sharply-pointed  lobes.  The  scales  are  not 
distinct.  Lewis  Coll,

Type.  Imperfect  fish ;  Geneva  Museum. 

A  species  nearly  as  large  as  the  type,  with  the  trunk  slightly 
deeper  in  proportion  to  its  length.  Pelvic  fins  wEen  adpressed  just 
reaching  the  anal  spines ;  dorsal  fin  with  2  or  3  spines  and  29  or 
30  articulated  rays,  the  length  of  the  longest  anterior  rays  not  ex¬ 
ceeding  half  the  depth  of  the  trunk  at  their  insertion  ;  anal  fin  with 
3  spines  and  19  articulated  rays,  not  extending  backwards  beyond 
the  dorsal  fin. 

The  type  specimen  of  the  so-called  Platax  brevis  is  evidently

caudal  fin ;  dorsal  fin  with  about  5  small  anterior  spines  and  from 
50  to  55  articulated  rays,  the  elevation  of  the  anterior  half  of  the 
fin  somewhat  less  than  twice  the  depth  of  the  trunk  at  its  insertion  ;

Caucasus  (Simonovich,  Batzevich,  and  Sorokin,  Material.  Geol. 
Kavkaza,  1875,  p.  162,  pis.  i.-iii.)  does  not  belong  to  this  genus, 
and  cannot  be  satisfactorily  determined  from  the  published 
description  and  figure. 


Genus  AMPHISTIUM,  Agassiz. 

[Poiss.  Foss.  vol.  v.  pt.  i.  1844,  p.  44.]

The  so-called  Amphistium  hozzianum  (Massalongo,  MS.)  from 
Monte  Bolca,  is  considered  to  be  identical  with  A.  paradoxiim  by 
Eellotti  (see  Massalongo,  Spec.  Photogr.  Anim.  Poss.  Agr.  Veron. 
1859,  p.  37,  pi.  xiii.  fig.  2),  but  regarded  as  a  distinct  species  by 
A.  de  Zigno  (Mem.  E,.  Istit.  Yeneto,  vol.  xxiii.  1887,  p.  14). 

The  following  species  are  not  represented  in  the  Collection,  and 
do  not  belong  to  this  genus,  the  first  probably  not  to  the  family 
Carangidae : — 

Amphistium  cluhium^  F.  Bassani,  Atti  E.  Accad.  Sci.  Yapoli  [2]

[Sitzungsb.  k.  Akad.  Wiss.,  math.-naturw.  Cl.  vol.  xi.  1854,  p.  135.] 

Trunk  irregularly  fusiform,  somewhat  deepened  ;  head  relatively 
large  and  distorted,  the  small  mouth  being  directed  upwards  ;  a 
very  large  supraoccipital  crest,  continued  forwards  beyond  the  orbit. 
Teeth  minute.  Pectoral  fins  well  developed  ;  pelvic  fins  with  two 
or  three  rays  much  elongated,  inserted  in  advance  of  the  pectorals  ; 
dorsal  fin  extending  along  the  greater  part  of  the  back,  with  very 
feeble  anterior  spines,  the  foremost  few  articulated  rays  much 
elongated,  the  others  low  and  fringe-like  ;  anal  fin  about  as  much 
extended  as  the  dorsal,  with  very  feeble  anterior  spines,  low  and 
fringe-like ;  caudal  fin  slightly  rounded  or  truncated.  Foremost 
anal  fin-support  much  expanded  at  its  lower  end.  Scales  cycloid,  of 
moderate  size,  none  enlarged  or  thickened. 

The  pelvic  fin-rays  in  this  genus  are  very  finely  divided,  as 
shown  by  a  specimen  described  below  (no.  P.  1990).  Kner  and 
Stein dachner  were  thus  probably  misled  in  their  determination  of 
8  or  9  rays  in  the  pelvic  fins  of  V.  elon^atus.

The  type  species,  attaining  a  length  of  about  0’2.  Length  of 
head  with  opercular  apparatus  slightly  less  than  maximum  depth  of 
trunk,  which  is  contained  twice  in  the  total  length  to  the  base  of 
the  caudal  fin.  Pectoral  fin  with  about  13  rays ;  dorsal  fin  with 
nearly  40  rays,  of  which  the  foremost  2  or  3  are  rudimentary  spines; 
anal  fin  slightly  more  extended  than  the  dorsal,  arising  just  in 
adyance  .of  the  latter,  with  about  30  rays,  of  which  the  foremost 
1  or  2  are  rudimentary  spines ;  caudal  fin  slightly  rounded.

Purchased,  1861. 

P.  1990.  Fine  small  specimen,  in  counterpart,  labelled  by  Agassiz. 

The  head  is  well  shown,  with  its  great  supraoccipital 
crest,  small  upturned  mouth,  and  traces  of  minute  teeth. 
There  are  about  8  branchiostegal  rays.  The  yertebrse  are 
eyidently  10  + 14  in  number ;  the  centra  are  much  con¬ 
stricted,  and  some  show  a  single  sharp  lateral  keel ;  the 
hinder  four  or  fiye  neural  spines  in  the  abdominal  region 
curye  forwards  at  their  upper  end.  The  clayicle  is  slender 
and  sigmoidally  bent,  with  a  long  rod-like  postclayicle 
extending  to  the  yentral  border  of  the  fish.  The  coracoid 
extends  downwards  to  the  clayicular  symphysis  by  a 
falciform  process  from  its  postero-inferior  angle.  The 
pelyic  fin-support  is  somewhat  expanded,  forked  an¬ 
teriorly,  and  is  in  contact  with  the  clayicle  at  the  two 
extremities  of  this  bifurcation.  The  anterior  spine  of 
the  pelvic  fin  is  very  small ;  the  length  of  the  two  (or 
possibly  three)  next  rays  equals  at  least  half  the  depth  of 
the  trunk  at  their  insertion ;  while  both  these  and  the 
succeeding  diminutive  rays  are  finely  divided  distally.  The 
rays  of  the  dorsal  and  anal  fins  are  not  very  satisfactorily 
displayed,  but  all  except  two  or  three  anterior  rudimentary

divided  distally.  The  length  of  the  foremost  articulated 
dorsal  fin-rays,  as  preserved,  equals  the  depth  of  the  trunk 
at  their  insertion  ;  but  the  fin  rapidly  diminishes  to  a  low 
fringe  behind.  The  foremost  dorsal  fin-support  has  an 
anterior  expansion,  and  there  are  two  free  fin-supports 
between  this  and  the  occipital  crest.  None  of  the  anal 
fin-rays  are  elongated.  The  caudal  fin  is  slightly  rounded 
behind.  Egerton  Coll.

spines,  closely  followed  by  a  more  extended  dorsal  of  articulated 
rays  ;  anal  fin  opposed  to  the  posterior  dorsal  and  of  equal  extent, 
preceded  by  two  short  and  separate  anal  spines  ;  caudal  fin  forked. 
Scales  thin  and  small,  thickened  or  enlarged  at  least  along  the 
caudal  portion  of  the  lateral  line ;  lateral  line  arched  in  front, 
straight  behind. 

Numerous  species  of  Caranx  are  common  in  tropical  and  tem¬

43448.  Head  and  trunk,  wanting  end  of  tail. 

Presented  hy  Kenneth  Murchison^  Esq.^  1872. 

The  undefined  name  Carangopsis  maximus  was  given  by  Agassiz 
(Heues  Jahrb.  1835,  p.  292)  to  a  fish  from  Monte  Bolca  in  the 
Paris  Museum,  originally  referred  to  Scomber  glauciis  by  G.  S.  Yolta, 
Ittiolit.  Veronese  (1796),  p.  xxxvii.  pi.  xxi. 

The  so-called  Cm'angoqysis  lanceolatus  (F.  Bassani,  Atti  Soc. 
Veneto-Trent.  Sci.  Nat.  vcl.  v.  1876,  p.  153,  and  Palaeont.  Italica, 
vol.  iii.  1898,  p.  77,  pi.  viii.  fig.  1),  founded  on  a  fish  from  Monte 
Bolca  in  the  Geological  Museum,  University  of  Padua,  does  not 
belong  to  the  family  Carangidse.  It  may  represent  a  species  of 
Myi'ipristls. 


Genus  DUCTOR^  Agassiz. 

[Poiss.  Foss.  vol.  V.  pt.  i.  1844,  p.  53.] 

Trunk  much  elongated  but  fusiform.  Head  much  elongated,  and 
supraoccipital  crest  insignificant ;  eye  large  ;  mouth  small  and  teeth 
minute  ;  preoperculum  with  fine  radiating  markings  and  apparently 
serrated;  branchiostegal  rays  7  or  8,  relatively  large.  Paired 
fins  small;  an  anterior  dorsal  fin  of  6  or  7  feeble  spines,  closely 
followed  by  a  more  extended  dorsal  of  articulated  rays ;  anal  fin  less 
extended  than  posterior  dorsal,  probably  with  two  small  feeble  spines 
in  front ;  caudal  fin  small.  Scales  very  small  and  uniform,  all 
antero-posteriorly  elongated ;  lateral  line  not  observable.

Poiss.  Foss.  vol.  V.  pt.  i.  1844,  p.  31)  from  the  Upper  Cretaceous  of 
Mt.  Lebanon. 

The  following  otolith  is  supposed  to  belong  to  a  member  of  this 
family — 

Otolithus  {Carangidarum')  americanus^  E.  Koken,  Zeitschr.

The  existing  genus  EcJieneis,  with  the  anterior  dorsal  fin  modified 
into  an  adhesive  disk,  is  usually  placed  with  the  Scombridae ;  but 
it  is  represented  by  an  extinct  species  in  the  Oligocene  slates  of 
Canton  Glarus,  Switzerland,  which  is  remarkable  as  exhibiting 
only  10  abdominal  and  13  caudal  vertebrae.  This  fish  is  known 
only  by  one  specimen  in  the  Berne  Museum,  which  has  the  disk 
narrower  and  a  little  further  back  than  in  the  typical  EcJieneis.  It 
is  described  as  Echeneis  glaronensis  by  A.  Wettstein,  Fischfauna 
Tertiaer.  Glarnerschief.  (Denkschr.  schweiz.  Palaeont.  Ges.  vol.  xiii. 
1886),  p.  82,  pi.  vii.  fig.  10,  and  is  discussed  by  R.  Storms,  Ann. 
Mag.  Nat.  Hist.  [6]  vol.  ii.  (1888),  p.  73.  The  new  generic  name 
Opisthomyzon  is  proposed  for  it  by  E.  D.  Cope,  Amer.  Nat.  vol.  xxiii 
(1889),  p.  355. 


Family  SCOMBRID^. 

Snout  not  produced  into  an  elongated  rostrum ;  no  supramaxillae 
gape  wide,  and  teeth  conical,  forming  a  more  or  less  powerful 
dentition.  Vertebrae  from  28  to  160  in  total  number;  centra  of 
abdominal  region  with  transverse  processes  in  fusiform  types,  but 
without  these  processes  in  the  more  elongate  t3’pes.  Pelvic  fins, 
when  present,  thoracic,  with  one  spine  and  not  more  than  five 
articulated  rays  ;  spinous  portion  of  dorsal  fin  more  extended  than 
articulated  portion ;  usuall}'’  finlets  behind  dorsal  and  anal  fins. 
Scales  small  or  absent,  and  no  bony  scutes ;  lateral  line  distinct. 

All  the  existing  members  of  this  family  are  marine,  most  of  them 
being  pelagic,  some  characteristic  of  the  deep  sea.  In  outward 
shape  and  the  development  of  the  median  fins,  the  genera  are  as

The  more  elongated  and  degenerate  types  are  those  inhabiting  great 
depths. 

All  the  known  fossil  Scombridae  occur  in  marine  deposits.

frontals.  Teeth  small  and  conical,  and  in  single  series  on  margin 
of  jaws,  minnte  and  clustered  on  vomer  and  palatines.  Vertebrae 
about  40  in  number,  the  centra  constricted,  with  two  lateral  pits 
separated  by  a  longitudinal  ridge  ;  all  haemail  arches  simple. 
Pectoral  fins  elongate,  but  not  extending  beyond  origin  of  anal ; 
pelvic  fins  small ;  dorsal  fins  scarcely  separated,  the  anterior  con¬ 
sisting  of  12  to  15  spines ;  posterior  dorsal  and  anal  fins  small  but 
elevated,  similar  and  opposite,  followed  by  8  to  12  detached  finlets  ; 
caudal  fin  deeply  forked,  with  slender  lobes.  Scales  very  small,

Chiavon,  Vicentin.  [Imperfect  fish;  Piovene  Coll., 
Lonedo.] 

The  fragmentary  fossils  described  under  the  following  names  do 
not  appear  to  belong  to  this  genus  : — 

Tliynnus  angustus,  H.  E.  Sauvage,  Ann.  Sci.  Nat.  [5]  vol.  xiv. 
(1870),  art.  no.  7,  p.  6,  and  Ann.  Sci.  Geol.  vol.  iv.  (1873), 
art.  no.  1,  p.  144,  fig.  21.  Auccis  (?),  D.  G.  Kramberger, 
Beitr.  Palaont.  Oesterr.-Engarns,  vol.  ii.  (1882),  p.  118. 
— Upper  Miocene  ;  Licata,  Sicily. 

Tliynnus  holcensis,  L.  Agassiz,  Neues  Jahrb.  1835,  p.  305,  and 
Poiss.  Eoss.  vol.  V.  pt.  i.  (1844),  p.  57  (undescribed). 
Scomber  tliynnus^  G.  S.  Yolta,  Ittiolit.  Veronese  (1796), 
p.  cxix.  pi.  xxvii.  {errore). — Upper  Eocene ;  Monte  Bolca. 
[Imperfect  fish  ;  Paris  Museum  of  Natural  History.] 
Tliynnus  (?)  proximus,  H.  E.  Sauvage,  loc.  cit.  1870,  p.  7,  and 
1873,  p.  146,  fig.  24. — Upper  Miocene  ;  Licata.  [Portion 
of  trunk.] 

Genus  EOTHYNNUS,  novum. 

Syn.  Coelocephalus,  L.  Agassiz,  Poiss.  Foss.  vol.  v.  pt.  ii.  1844,  p.  139 
(name  only) 

A  genus  known  only  by  the  head,  which  is  essentially  identical 
with  that  of  Tliynnus,  but  seems  to  be  deeper  in  proportion  to  its 
width.  Teeth  on  margin  of  jaws  very  small  and  clustered  in  more 
than  one  series. 

Eothynnus  salmoneus,  sp.  nov. 

1844-45,  Coelocephalus  salmoneus,  L.  Agassiz,  Poiss.  Foss.  vol.  v.  pt.  ii. 
p.  139,  and  Rep.  Brit.  Assoc.  1844,  p.  308  (name  only). 

Type.  Imperfect  cranium  ;  British  Museum. 

The  type  species,  with  head  and  opercular  apparatus  sometimes 
nearly  0*25  in  length.  Width  of  cranium  at  occiput  about  two 
thirds  maximum  depth  of  head.  Maximum  depth  of  operculum 
about  twice  its  greatest  width. 

Form.  ^  Loc.  Lower  Eocene  (London  Clay) :  London  Basin. 

P.  623.  Very  imperfect  cranium,  labelled  byEgerton  as  intended  to  be 
the  type  specimen  of  this  species ;  Sheppey.  Egerton  Coll. 

28757.  Large  head,  with  some  anterior  vertebrae  much  like  those 
of  Thynnus  ;  Sheppey.  Purchased,  1853. 

^  This  generic  name  has  been  employed  for  an  existing  Macrurid  by  Gilbert 
&  Cramer,  Proc.  U.S.  Nat.  Mus.  vol.  xix.  (1897),  p.  422. 


458 


ACTINOPTERTGII. 


19114.  Smaller  head,  less  distorted,  showing  most  of  the  principal 
characters ;  Sheppey.  The  three  anterior  vertebral  centra 
are  shown  in  position. 

Presented  hy  Rev.  F.  W.  Hope,  1845. 

P.  1750.  Imperfect  head,  partly  decaying,  showing  the  jaws  and 
the  bases  of  the  clustered  minute  teeth  on  the  premaxillse ; 
Sheppey.  Egerton  Coll. 

There  seem  to  be  no  satisfactory  characters  by  which  the 
following  specimens,  from  the  London  Clay  of  Sheppey,  can  be 
generically  separated  from  Eothynnus  : — 

38900.  Imperfect  head  with  opercular  apparatus,  deeper  than  in 
E.  scdmoneus.  BowerhanTc  Coll. 


P.  629.  Small  imperfect  head,  similarly  deepened,  marked  hy 
Egerton  as  intended  to  be  the  type  specimen  of  Rhonclius 
carangoides,  Agassiz  (named  in  list  in  Eep.  Brit.  Assoc. 
1844  [1845],  p.  308)  Egerton  Coll. 

P.  9454.  Hinder  part  of  similar  small  head.  Egerton  Coll. 

P.  1744.  Hinder  portion  of  larger  head  with  remains  of  opercular 
apparatus,  marked  “  KJionchus  n.s.”  by  Egerton. 

Egerton  Coll. 

35057.  Hinder  portion  of  similar  head  with  opercular  apparatus. 

Purchased,  1861. 


P.  628.  Hinder  portion  of  cranium,  apparently  with  crests  worn 
^away,  marked  by  Egerton  as  intended  to  be  the  type 
specimen  of  Phalacrus  cyhioides,  Agassiz  (named  in  list 
in  Eep.  Brit.  Xssoc.  1844  [1845],  p.  308).  Egerton  Coll. 


• 


To  Eothynnus  may  also  probably  be  referred  the  vertebrae  from  the 
London  Clay  of  Sheppey  in  the  Eoyal  College  of  Surgeons,  named 
Thynnus  toliapicus,  E.  Owen,  Catal.  Eoss.  Eept.  &  Pisces  (1854), 
p.  174,  no.  697.  The  following  are  similar  specimens  : — 


36117.  Three  terminal  caudal  vertebrae  ;  London  Clay,  Sheppey. 

Purchased,  1861. 

38885.  Three  caudal  vertebrae  ;  Sheppey.  BowerhanTc  Coll. 

P.  4300  a,  P.  4301.  Three  caudal  vertebrae  ;  Sheppey. 

Enni-sTcillen  Coll. 


^  Apparently  the  same  as  a  specimen  in  the  Eoyal  College  of  Surgeons, 
named  Cariniceps  compressus,  E.  Owen,  Oatal.  Foss.  Eept.  &  Pisces  (1854), 
p.  165,  no.  663.

Type.  Imperfect  fish ;  Museum  of  Natural  History,  Paris. 

A  small  species,  attaining  a  length  of  about  0‘35.  Length  of 
head  with  opercular  apparatus  somewhat  exceeding  maximum 
depth  of  trunk,  and  slightly  less  than  one  third  the  total  length  of 
the  fish  to  the  base  of  the  caudal  fin.  Teeth  slender.  Vertebrae 
15  in  the  abdominal,  15  in  the  caudal  region.  Posterior  dorsal 
and  anal  fins  apparently  with  10  articulated  rays  followed  by 
8  finlets. 

This  imperfectly  known  species  differs  remarkably  from  the 
existing  C.  maculatum  in  the  number  of  vertebrae,  the  latter  having 
45.  The  number  of  vertebrae  is  not  recorded  in  other  species.

Cybium  excelsum,  sp.  nov. 

[Text-figure  15.] 

Type.  Eemains  of  head ;  British  Museum. 

A  very  large,  imperfectly  known  species,  with  skuU  nearly  0*4  in 
length.  Teeth  broad  and  much  laterally  compressed,  not  very 
variable  in  size,  those  of  front  portion  of  premaxilla  scarcely  smaller 
than  the  anterior  mandibular  teeth.  Anterior  end  of  premaxilla 
more  deepened  and  less  attenuated  than  in  the  next  species  ;  the 
whole  premaxilla  probably  longer  in  proportion  to  its  depth  than 
in  the  Eocene  Cyhium  hleeheri. 

Form.  ^  Log.  Upper  Eocene  (Barton  Clay) :  Barton  Cliff,  Hamp¬

discovered  by  Barbara,  Marchioness  of  Hastings,  in  Barton 
Cliff.  So  far  as  it  can  be  compared,  the  skull  resembles 
that  of  Cyhium.  Both  premaxill®  are  imperfectly  pre¬ 
served,  and  that  of  the  right  side  is  shown  from  the  outer 
aspect,  of  two  thirds  the  natural  size,  in  fig.  15  a.  The 
left  dentary  bone  is  more  fragmentary,  but  its  symphysial 
end,  shown  in  fig.  15  b,  bears  two  teeth.  The  centrum  of 
the  first  vertebra  is  distinguishable,  and  portions  of  other 
typical  centra  occur  among  the  remains.  Egerton  Coll.

Type.  Portions  of  jaws;  British  Museum. 

A  very  large  species  known  only  by  the  jaws,  with  mandible 
about  0'45  in  length.  Teeth  broad  and  much  laterally  compressed, 
those  of  front  portion  of  premaxilla  considerably  smaller  than  the 
anterior  mandibular  teeth.  Anterior  end  of  premaxilla  less 
deepened  and  more  attenuated  than  in  C.  eoccelsum  and  C.  hleeheri.

A  genus  known  only  by  the  head.  Cranium  rather  short  and 
broad  ;  fossae  for  lateral  muscles  of  trunk  extending  forwards  much 
beyond  the  hinder  margin  of  the  frontals  to  a  point  above  the 
middle  of  the  orbit;  frontals  nearly  as  broad  as  long,  marked  with 
rugosity  laterally,  sharply  depressed  mesially  just  in  front  of  the 
posterior  fossae,  and  the  hinder  part  of  their  median  suture  at  the 
anterior  end  of  the  low  supraoccipital  ridge  gaping  to  form  a  small 
vacuity.  Teeth  on  margin  of  jaws  rather  large,  stout,  conical,  and 
well-spaced,  not  much  laterally  compressed ;  minute  teeth  on 
vomer.

— o/ 


An  extinct  genus  comprising  large  species  known  only  by  portions 
of  skull  and  dentition.  Teeth  large  and  conical,  not  laterally 
compressed,  in  single  series  on  margin  of  jaws  [and  on  palatine  bone, 
according  to  Dollo  and  Storms]. 

The  dentition  is  more  powerful  and  the  premaxillae  are  relatively 
larger  than  in  the  existing  genus  Pelamys.

Type.  Imperfect  fish. 

A  slender  species  attaining  a  length  of  over  one  metre.  Length 
of  head  with  opercular  apparatus  contained  eight  times,  maximum 
depth  of  trunk  about  nineteen  times  in  the  total  length  of  the  fish 
to  the  base  of  the  caudal  fin.  About  12  teeth  on  the  margin  of 
each  jaw  above  and  below  ;  one  enlarged  at  anterior  end  of  pre¬ 
maxilla  ;  those  of  middle  of  dentary  twice  as  high  as  those  in  front 
and  behind  ;  the  largest  more  or  less  recurved.  Vertebrae  32  to  35 
in  the  abdominal,  72  to  75  in  the  caudal  region.  Pectoral  fins  un¬ 
usually  large,  the  length  of  the  two  lowest  rays  equalling  twice  the 
depth  of  the  trunk  ;  dorsal  fin  arising  above  first  vertebra,  termina¬ 
ting  over  sixth  from  caudal  fin,  and  its  anterior  10  or  12  rays  the 
longest ;  anal  fin  terminating  opposite  end  of  dorsal ;  caudal  fin 
larger  than  in  the  existing  species. 

This  is  the  tj^pe  species  of  Anenchelum.  The  known  examples 
are  very  variously  distorted,  and  it  is  difficult  to  determine  its 
exact  proportions.

anal  fins  much  extended,  the  greater  part  consisting  of  feeble 
spines  ;  caudal  fin  distinct  and  well  developed.  Scales  thin  and 
cycloid,  or  absent. 

An  imperfectly  known  extinct  family,  inhabiting  the  seas  of  the 
Eocene,  Oligocene,  and  Miocene  periods.  The  precise  constitution 
of  the  cranial  rostrum  is  undetermined.

Articulation  of  mandible  beneath  anterior  border  of  orbit,  and 
slender  jaws  nearly  of  equal  length;  teeth  apparently  absent; 
preoperculum  large  and  triangular,  ornamented  with  numerous 
radiating  grooves  ;  operculum  quadrangular.  Vertebrae  about  25 
in  the  abdominal,  35  in  the  caudal  region.  Pectoral  fins  small  and 
delicate  ;  pelvic  fins  large,  directly  beneath  the  pectorals,  each  with 
6  rays  ;  dorsal  fin  extending  almost  the  whole  length  of  the  back, 
its  spines  consisting  of  imperfectly-fused  right  and  left  halves,  and 
as  numerous  as  the  vertebrae  below  them  ;  anal  fin  also  very  ex¬ 
tensive,  the  greater  part  co-nsisting  of  spines  resembling  those  of  the 
dorsal ;  caudal  fin  forked.  Dorsal  and  anal  fin-spines  supported  by 
small  fan-shaped  bones,  which  are  strengthened  by  three  radiating 
ribs,  the  shortest  extending  along  the  margin  of  the  trunk,  the 
others  diverging  towards  the  vertebral  axis.  Scales  small  and 
ovoid.

Type.  Imperfect  fish. 

The  type  species,  attaining  a  length  of  about  0*8.  Complete 
length  of  head  with  opercular  apparatus  little  less  than  one  half 
that  of  the  vertebral  column ;  maximum  depth  of  trunk  contained 
about  14  times  in  total  length  of  fish.  Neural  and  haemal  spines 
of  vertebrae  straight  and  vertical  in  anterior  part  of  caudal  region. 

Nearly  50  dorsal  fin-spines,  the  length  of  the  longest  about  equalling 
that  of  10  vertebrae ;  15  to  18  short  divided  rays  in  the  hinder  part 
of  the  dorsal  fin ;  anal  fin  with  about  35  spines  and  32  divided  rays, 
the  spines  gradually  increasing  in  length  to  the  middle  of  the  fin 
where  they  are  longer  than  the  dorsal  spines. 

Almost  all  the  known  fossilised  examples  of  this  species  are  con¬ 
siderably  distorted,  and  it  is  difficult  to  determine  the  exact  pro¬ 
portions  of  the  fish.  The  accompanying  restoration  (fig.  17)  seems 

to  be  approximately  correct.  (lai

by  distortion,  is  much  obscured  by  matrix,  the  false 
appearance  of  a  large  crest  on  the  head  in  the  figure  being 
due  to  this  circumstance.  A  lithographed  plate  of  this 
specimen  was  published  by  the  Earl  of  Enniskillen  (when 
Lord  Cole)  in  1820.  Egerton  ^  Enniskillen  Colls.

Type.  Imperfect  fish  ;  British  Museum. 

A  species  attaining  a  length  of  about  0-6.  Head  depressed,  its 
maximum  depth  about  two  thirds  that  of  the  trunk ;  length  from 
end  of  snout  to  anterior  border  of  orbit  equalling  nearly  one  quarter 
of  total  length  of  fish  to  base  of  caudal  fin ;  mandible  not  quite  half 
as  long  as  rostrum.  Length  of  longest  dorsal  fin-spines  less  than 
half  as  great  as  depth  of  trunk  at  their  insertion ;  soft  dorsal  fin 
beginning  at  eleventh  vertebra,  soft  anal  at  fourteenth  vertebra 
from  caudal  fin.  ^

and  anal  fins  had  the  same  extent  as  in  H.  colei ;  and 
there  is  no  evidence  that  the  supports  of  the  dorsal  fin-

Family  XIPHIIDiE. 

Trunk  fusiform,  with  much-contracted  caudal  pedicle  and  large, 
forked  caudal  fin  ;  skeleton  very  robust.  Premaxillae  produced  into 
an  elongated  rostrum  and  fused  together  towards  their  anterior 
extremity ;  dentition  feeble  or  absent.  Vertebrae  24  to  26  in 
number,  about  half  being  caudal  .;  the  centra  firmly  united,  and  the 
neural  and  baemal  spines  expanded  into  laminae.  Pectoral  fins  of 
moderate  size  ;  pelvic  fins  with  less  than  5  articulated  rays,  or 
entirely  absent ;  dorsal  fin  much  extended,  with  few  anterior  spines, 
a  small  posterior  portion  sometimes  separated ;  anal  fin  also  ex¬ 
tended,  sometimes  with  small  separate  posterior  portion.  Squama- 
tion  more  or  less  discontinuous  or  absent.  Air-bladder  large. 

“  Sword-fishes  ”  are  common  in  all  tropical  and  subtropical  seas, 
and  three  genera  are  distinguished  as  follows  : — 

Rostrum  rounded  in  section  ;  teeth  minute,  persistent ; 
pelvic  fins  with  2  or  3  rays.;  dorsal  fin  much  elevated, 

undivided  ;  scales  present  . .  Ilistiojyhoriis. 

Rostrum  rounded  in  section ;  teeth  minute,  persistent ; 
pelvic  fins  a  single  spine ;  dorsal  fin  not  deeper  than 

trunk,  divided  in  adult;  scales  present  . . ,  Tetrapturus, 

Rostrum  much  depressed,  a  flattened  blade ;  teeth  absent 
in  adult;  pelvic  fins  absent;  dorsal  fin  much  elev^ated, 
usually  divided  in  adult ;  scales  absent  in  adult. .  .  .  Xiphias. 

The  known  fossils  are  too  imperfect  to  be  referred  with  certainty 
to  their  respective  genera.  Most  of  them  probably  belong  to 
Histiojpliorus  or  Tatrajptuvus  but  at  least  one  genus  from  the 
Eocene  is  distinguished  from  the  existing  members  of  the  family 
by  the  form  of  the  cranial  roof  and  the  duplication  of  each  nutritive 
canal  in  the  premaxillae  {Xiphiorhynchus).

ACTINOPTEETGII. 


28711.  Imperfect  anterior  portion  of  cranium,  wanting  rostrum, 
shown  of  the  natural  size  from  the  upper  and  left  lateral 
aspects  in  PI.  XIX.  figs.  1,  I  a  ;  Shepp^y.  The  bones 
exhibit  a  coarsely  fibrous  texture.  The  greater  portion  of 
the  left  frontal  (/r.)  is  seen,  with  a  fragment  of  that  of 
the  right  side.  In  front  of  these  there  occurs  a  median 
element  {eth.\  which  seems  to  be  a  membrane-bone  on 
the  ethmoidal  region  rather  than  the  mesethmoid  itself. 
Another  median  pair  of  bones,  evidently  long  and  narrow, 
quite  at  the  base  of  the  rostrum,  are  doubtless  to  be 
interpreted  as  nasals  (na.).  The  position  of  the  orbit  is 
marked  by  remains  of  the  ossified  sclerotic  {sd.).  Shortly 
in  advance  of  this  a  trace  of  the  prefrontal  (ectethmoid) 
projects  through  the  matrix  on  the  left  side  (pr./.),  while 
its  fellow  is  still  better  exposed  on  the  right.  The 
maxilla  {mx.)  is  preserved  on  both  sides,  and  its  upper 
expansion  is  articulated  with  the  antero-external  border 
of  the  frontal,  besides  being  almost  or  quite  in  contact 
with  the  ethmoidal  plate,  and  distinctly  in  contact  with 
the  hinder  part  of  the  outer  border  of  the  nasal.  The 
rod-like  backward  extension  of  the  maxilla  beneath  the 
orbit  is  shown  on  the  right  side,  though  it  is  broken  away 
from  the  main  part  of  the  bone.  Remains  of  the  pre¬ 
maxilla,  which  is  much  smoother  than  the  other  bones, 
are  seen  on  both  sides.  Part  of  this  element  occurs  in  its 
natural  position  on  the  left  {pmx.')  ;  while  the  fragments 
on  the  right  show  that  it  bore  clustered  minute  teeth 
(fig.  1  h)  and  completely  excluded  the  maxilla  from  the 
gape.  Purchased,  1853. 

32387.  Hinder  half  of  cranium  in  hard  nodule,  exposing  the  cranial 
roof,  which  is  shown  of  the  natural  size  in  PI.  XIX. 
fig.  2  ;  Sheppey.  The  two  pairs  of  fossae  for  the  forward 
extension  of  the  lateral  muscles  of  the  trunk  are  very 
small  and  restricted  to  the  occipital  border.  The  roof  is 
gently  and  regularly  convex.  The  supraoccipital  {s.occ.) 
is  large  and  extends  forwards  to  the  frontals  ;  it  is  a  little 
expanded  in  front,  and  bears  a  small  median  vertical  crest 
behind.  Its  postero-external  angle  is  in  contact  with  the 
epiotic  {ep.o.),  which  is  large  and  prominent  but  onlj^ 
preserved  on  the  right  side.  The  parietals  (pa.)  are  long 
and  narrow  bones  extending  nearly  as  far  forwards  as  the 
supraoccipital ;  they  are  fianked  by  an  equally  long  and 
narrow  pair  of  squamosals  (s^'.).  The  otic  region  beneath

the  latter  is  evidently  well  ossified,  and  the  postfrontal  or 
sphenotic  (pt.f.)  is  seen  on  both  sides.  The  frontal  hones 
(/r.)  are  incomplete  anteriorly.  All  the  bones  have  the 
peculiar  squamous  and  radiating  texture,  well  represented 
in  the  figure.  Purchased,  1857. 

36133.  Two  imperfect  rostra,  one  shown  in  outline  in  fig.  18,  no.  1

nos.  1  a,h.  Cl  Sheppey.  The  proximal  transverse  section 
of  the  second  specimen  (no.  la)  exhibits  incomplete 
fusion  of  the  premaxillse,  and  a  large  median  cavity  with 
which  the  upper  pair  of  premaxillary  canals  are  confluent. 
The  next  transverse  section  (no.  1  h),  which  corresponds 
approximately  with  the  line  marked  h  in  no.  1,  shows  the 
premaxillse  fused  and  the  central  cavity  small,  with  two 
pairs  of  nutritive  premaxillary  canals.  The  third  trans¬ 
verse  section  (no.  1  c)  has  the  canals,  but  not  the  central 
cavity.  Purchased,  1861.

Anterior  teeth  acutely  conical,  minute  and  clustered,  with  few 
large  canines ;  hinder  teeth  rounded  and  molariform,  in  two  or 
more  series.  Preoperculum  fimbriated,  not  serrated.  Dorsal  fin 
with  11  to  13  spines.  Scales  of  moderate  size,  finely  serrated,  ex¬ 
tending  over  the  operculum  and  cheek,  and  forming  a  sheath  at  the 
base  of  the  dorsal  fin. 

Existing  in  the  Mediterranean  and  on  the  eastern  shores  of  the 
Atlantic. 

There  are  no  fossils  in  the  Collection  certainly  referable  to  this 
genus,  and  those  described  as  follows  are  not  generically  determin¬ 
able  : —

Pagellus  de  stefanii  and  Pagelliis  peruzzii  are  undefined  names 
given  to  fishes  from  the  Upper  Miocene  of  Gabbro,  Tuscany 
(de  Bosniaski,  Atti  Soc.  Tose.  Sci.  Nat. — Proc.-Verb.  vol.  i.  1878, 
p.  xix). 

Genus  PAGRUS,  Cuvier. 

[Pegne  Animal,  vol.  ii.  1817,  p.  272,] 

Stout  conical  prehensile  teeth  at  the  symphysis  of  the  jaws,  and 
two  series  of  large  rounded  molariform  teeth  behind.  Preoperculum 
not  serrated.  Dorsal  fin  with  12  (rarely  11)  spines.  Scales  of 
moderate  size,  very  finely  serrated,  extending  over  the  operculum 
and  cheek,  and  forming  a  sheath  at  the  base  of  the  dorsal  fin. 

Almost  cosmopolitan  on  existing  coasts. 

There  do  not  appear  to  be  any  recognisable  remains  of  extinct 
forms  of  this  genus  in  the  Collection,  but  various  fossils  have  been 
described  as  follows  : —

As  Pagrus,  but  molariform  teeth  in  three  or  more  series,  usually 
irregular. 

Almost  cosmopolitan  on  existing  coasts. 

This  genus  is  not  represented  in  the  Collection  by  any  specifically 
determinable  fossil  remains,  and  the  extinct  forms  described  as 
follows  are  not  very  satisfactorily  determined  : —

Family  CHROMID^. 

Narial  opening  single  on  each  side,  and  scales  usually  ctenoid, 
otherwise  as  Labridag. 

Tropical  and  subtropical  freshwater  fishes,  very  numerous  and 
varied  in  the  existing  fauna  but  scarcely  known  among  fossils.

boiirhood  of  coral  reefs.  A  few  genera  seem  to  date  back  to  the 
early  part  of  the  Tertiary  period,  when  they  ranged  further  north 
than  at  the  present  day.  Only  two  extinct  genera,  Pygoeus  and 
Proantigonia,  are  provisionally  placed  here. 

Genus  PYG.ffiUS,  Agassiz. 

[Poiss.  Foss.  vol.  iv.  1838,  p.  16.] 

An  imperfectly  known  extinct  genus,  with  spinous  portion  both 
of  dorsal  and  anal  fin  as  much  extended  as  articulated  portion. 
Dorsal  fin  continuous  and  occupying  nearly  the  whole  of  the  back, 
gently  rising  in  front,  as  gently  falling  behind ;  anal  fin  with  8  or 
9  spines,  similar  to  dorsal  but  less  extended. 

The  genus  is  supposed  to  be  related  to  the  Aphredoderidae  by 
Cope  (Vert.  Tert.  Form.  West,  1884,  p.  85),  but  no  known  speci¬ 
men  clearly  exhibits  more  than  5  articulated  rays  in  the  pelvic 
fins.

Type.  Imperfect  fish  ;  British  Museum. 

A  small  species  about  0'04  in  length.  Maximum  depth  of  trunk 
somewhat  less  than  its  length  from  pectoral  arch  to  base  of  caudal 
fin ;  length  of  head  with  opercular  apparatus  contained  twice  in 
same  length  of  trunk.  Dorsal  fin  with  14  spines  and  15  articu¬ 
lated  rays,  the  latter  not  longer  than  the  former ;  anal  fin  with 
9  spines  and  11  articulated  rays.

<562  ACTINOrTEETGII. 

Family  ACRONFTn^D^.^ 

Trunk  deepened.  Maxilla  fused  with  premaxilla;  incisiform 
teeth  in  single  series.  Vertebrae  9  or  10  m  abdominal,  13  or  14 
in  caudal  region.  Pelvic  bones  firmly  united  ;  anal  fin  with  2  or  3 
spines.  Scales  minute,  more  or  less  ctenoid  or  spinous. 

Herbivorous,  perhaps  partly  carnivorous,  fishes  common  in  tropical 
seas  in  the  neighbourhood  of  coral  reefs.  Three  extinct  genera 
probably  belong  to  this  family,  while  the  existing  Acantliurus  and 
Naseus  seem  to  date  back  to  the  Eocene  period,  when  they  ranged 
far  north  into  the  present  temperate  zone.

Sci.  [3]  vol.  vi.  no.  4,'1:885,  p.  3. 

Teeth  very  stout,  apparently  in  single  series.  Pectoral  fins 
delicate ;  [pelvic  fins  unknown ;  ]  six  or  seven  very  large  dorsal 
spines  in  spaced  series  extending  from  above  the  eye  along  more 
than  half  of  the  dorsal  border,  gradually  decreasing  in  size 
backwards ;  posterior  dorsal  and  anal  fins  relatively  small  and 
short-based ;  caudal  fin  rounded.  Dermal  tubercles  minute. 

This  extinct  genus  is  known  only  by  two  imperfect  specimens 
from  the  Upper  Eocene  of  Monte  Bolca,  near  Yerona;  the  first 
being  in  the  Paris  Museum  of  Natural  History,  described  and 
figured  by  Agassiz  (Poiss.  Foss.  vol.  v.  pt.  i.  1839-44,  p.  107, 
pi.  xxxix.  fig.  1)  under  the  name  of  Spinacanthiis  hlennioides ;  the 
second  in  the  Yerona  Museum,  described  and  figured  by  A.  de 
Zigno  (Mem.  Soc.  Ital.  Sci.  [3]  vol.  vi.  no.  4,  1885,  p.  4,  figs.  1,  2) 
under  the  name  of  Protohalistum  imperiale.  The  first  specimen 
differs  from  the  second  in  exhibiting  serrations  on  the  anterior 
dorsal  spine.  It  was  originally  ascribed  in  error  to  Blennius 
ocellaris  by  G.  S.  Yolta  (Ittiolit.  Yeronese,  1796,  p.  Ixiv.  pi.  xiii. 
fig.  2),  and  subsequently  named  Blennius  cuneiformis  by  H.  D.  de 
BlainviUe  (Nouv.  Diet.  d’Hist.  Nat.  vol.  xxvii.  1818,  p.  359),

Genus  OSTRACIOINT^  Linmeus. 

[Syst.  Nat.  ed.  10,  1758,  p.  330.] 

Teeth  much  elongated,  in  single  series.  Yertehrae  reduced  to  14. 
Pectoral  fins  small,  and  pelvic  pair  absent ;  no  dorsal  spines,  the 
posterior  dorsal  and  anal  fins  small  and  opposed  ;  caudal  fin  rounded. 
Greater  portion  of  trunk  encased  in  firmly-united  polygonal  bony 
plates. 

The  following  small  extinct  species,  not  represented  in  the

The  name  Glyptoceplialus  radiatus  is  proposed  by  Agassiz  (Poiss. 
Eoss.  vol.  ii.  pt.  ii.  1844,  p.  264)  for  the  tuberculated  skull  of  a 
supposed  member  of  the  Balistidse  from  the  London  Clay  of  Sheppey, 
said  to  have  been  placed  in  the  British  Museum  by  Konig  and 
labelled  by  him  Ephippus  oivenii.  This  is  the  head  of  a  Siluroid 
fish  already  described  above  (p.  330)  as  Bucklandium  diluvii. 


Family  GYMNODONTIDJE. 

Trunk  deepened.  Maxilla  fused  with  premaxilla ;  no  separate 
teeth,  but  often  dental  plates  imbedded  in  the  bone  of  the  jaw, 
these  continually  replaced  by  vertical  successors.  Vertebrae  usually 
much  reduced.  No  spines  in  dorsal  or  anal  fins.  Skin  usually 
with  small  spines  or  spinous  bony  plates,  sometimes  naked. 

Chiefly  tropical  and  sub-tropical  marine  fishes,  most  of  them 
surface-dwellers  and  capable  of  inflating  their  body  by  filling  the 
distensible  oesophagus  with  air.  A  few  Tetrodonts  live  in  large 
rivers.  No  clearly  recognisable  extinct  genera  are  known.

Genus  ORTHAGORISCUS,  Bloch  &  Schneider. 

[Syst.  Ichthyol.  1801,  p.  510  {Ortliragorisciis).'] 

Trunk  much  laterally  compressed,  truncate  behind.  Each  jaw 
fused  at  symphysis,  without  dental  plates.  Dorsal  and  anal  fins 
acuminate  in  front,  meeting  round  the  atrophied  tail.  No  dermal 
armour. 

The  species  of  this  genus  attain  a  very  large  size,  and  are 
almost  unknown  among  fossils. 

The  undescribed  Ortliagoriscus  chelonopsis  (P.  J.Yan  Beneden,  Bull. 
Acad.  Boy.  Belg.  [3]  vol.  vi.  1883,  p.  133),  from  the  Pliocene  Crag 
of  Antwerp,  is  represented  by  large  typical  jaws  in  the  Brussels 
Museum.  The  so-called  jaw  of  Ortliagoriscus  recorded  from  the 
Sussex  Chalk  by  E.  Dixon  (Geol.  Sussex,  1850,  p.  xiii.  pi.  xxxii. 
figs.  3,  4)  seems  to  be  a  Chelonian  dentary  bone  (A.  S.  Woodward, 
Proc.  Geol.  Assoc,  vol.  x.  1888,  p.  276). 

The  following  specimen  probably  belongs  to  this  genus : —

Pectoral  fins  with  much  extended  base  on  flank ;  pelvic  fins 
thoracic,  never  with  more  than  five  articulated  rays  in  addition  to 
the  spine.  One  bone  of  the  circumorbital  ring  modified  into  a  bony 
stay  between  it  and  the  armoured  preoperculum.

and  clavicle  are  in  contact. 

Vertebral  transverse  processes  short  or  absent; 
no  anal  fin-spines  ;  scaly  or  only  with 
bony  plates  along  lateral  line. .........  TaiGLiDiE  (p.  585). 

Family  SCORP^NIDiE. 

Head  more  or  less  armed  with  spines  ;  mouth  large  and  terminal, 
with  minute  teeth.  Vertebrae  24  to  31  in  total  number,  those  of 
abdominal  region  with  transverse  processes  supporting  ribs.  Post¬ 
temporal  bone  free  from  cranium,  and  supraclavicle  normal. 
Large  pectoral  fins  with  pelvic  fins  directly  beneath ;  dorsal  fin 
much  extended,  with  8  to  16  strong  spines ;  anal  fin  with  3  spines. 
Trunk  covered  with  a  regular  squamation  or  naked. 

These  are  marine  fishes  of  wide  distribution  and  varied  habit. 
Five  supposed  extinct  genera  are  known  by  unsatisfactory  frag¬ 
ments,  but  only  one  of  them  is  represented  in  the  Collection. 

A  figure  of  the  skeleton  of  the  existing  Sco7'poena  is  given  by 
Agassiz,  Poiss.  Foss.  vol.  iv.  pi.  L,  fig.  2. 

Genus  AMPHERISTUS,  Konig.

Syn.  Goniognathus,  L.  Agassiz,  Poiss.  Foss.  vol.  v.  pt.  i.  1844,  p.  63 
(name  only). 

An  apparently  extinct  genus,  known  only  by  remains  of  the 
head,  vertebral  column,  and  scales.  Orbit  very  large ;  interorbital 
portion  of  cranial  roof  concave,  with  a  pair  of  small  prominences 
above  the  hinder  part  of  the  orbital  rim ;  only  two  pairs  of  short 
longitudinal  ridges  on  the  postorbital  portion  of  the  frontal  region, 
forming  an  incomplete  W ;  lower  border  of  mandible  sharply  bent 
inwards.  Preoperculum  with  5  broad  spines ;  suborbital  stay 
probably  very  stout.  Vertebrse  probably  about  24  in  total  number.

Family  OOTTIDAl. 


Head  usually  broad  and  depressed,  with  narrow  interorbital 
region;  mouth  terminal,  with  minute  teeth.  Vertebrae  24  to  50 
in  total  number,  most  of  those  of  abdominal  region  with  small 
transverse  processes,  but  ribs  attached  to  centra  behind  these. 
Post-temporal  bone  free  from  cranium,  and  supraclavicle  normal. 
Large  pectoral  fins,  with  pelvic  fins  directly  beneath ;  extended 
dorsal  fin  usually  subdivided  into  two  parts,  the  anterior  consisting 
of  6  to  18  slender  spines  ;  anal  fin  without  spines.  Trunk  covered 
with  a  regular  squamation  or  small  prickles  or  naked. 

Small  littoral  fishes,  almost  universally  distributed,  sometimes 
occurring  in  freshwater.  The  only  two  known  extinct  genera  have 
a  regular  squamation. 

Descriptions  and  figures  of  the  skeleton  of  existing  Cottidae  are 
given  by  C.  Girard,  ‘A  Monograph  of  the  Cottoids,’  Smithson. 
Contrib.  vol.  hi.  art.  no.  3  (1850). 


Genus  EOCOTTUS,  novum. 

Preoperculum  with  large  antrorse  spines  on  lower  limb.  Vertebrae 
about  10  in  the  abdominal,  14  in  the  caudal  region.  Pectoral  fins 
very  delicate ;  pelvic  fins  relatively  large,  with  one  slender  spine 
and  5  articulated  rays  ;  dorsal  fins  continuous,  the  anterior  portion 
comprising  about  8  relatively  short  spines  ;  anal  fin  with  8  to  10 
rays ;  caudal  fin  rounded.  Small  scales  completely  covering  trunk. 

An  extinct  genus  known  only  by  one  species  from  the  marine 
Upper  Eocene  of  Italy.  According  to  Heckel  (Sitzungsb.  k.  Akad. 
AY  iss.,  math.-naturw.  Cl.  vol.  ii.  1850,  p.  148),  this  species  is 
closely  related  to  Callipteryx  ;  but  it  is  distinguished  from  that 
genus  by  the  presence  of  scales  and  the  short  and  stout  form  of 
the  neural  arches  in  the  abdominal  region.

Form,  ^  Loc.  Upper  Eocene  :  Monte  Bolca,  near  Verona. 

P.  1968,  P.  3947.  Fine  specimen,  in  counterpart.  The  head  is 
much  crushed,  but  the  inferior  spines  of  the  preoperculum 
are  well  shown.  There  are  clearly  only  10  abdominal 
and  14  caudal  vertebrae  ;  the  former  with  very  short  and 
stout  neural  arches  and  with  robust  transverse  processes 
overlapped  by  short  and  stout  ribs.  There  are  traces  of 
the  delicate  pectorals,  and  all  the  other  fins  are  well 
preserved.  The  caudal  fin  is  supported  by  five  expanded 
haemal  arches,  the  uppermost  the  largest.  The  scales  are 
seen  and  exhibit  fine  radiating  markings  in  their  covered 
portion,  but  their  hinder  margin  is  not  clearly  observable. 
The  lateral  line  is  conspicuous.

585 


Genus  COTTX7S  (Artedi),  Linnaeus. 

[Syst.  Nat.  ed.  10,  1758,  p.  264.] 

Head  feebly  armed  ;  preoperculum  more  or  less  spiny  ;  6 
branchiostegal  rays.  Vertebrae  about  30  to  35  in  number,  more 
than  half  being  caudal.  Pelvic  fins  with  one  small  spine  and  four 
articulated  rays  ;  dorsal  fins  separate,  the  first  with  6  to  10  slender 
spines ;  anal  fin  with  9  to  20  rays ;  caudal  fin  rounded.  Scales 
absent,  but  minute  prickles  sometimes  present. 

Characteristic  of  the  freshwaters  and  shores  of  northern  tem¬ 
perate  regions. 

There  do  not  appear  to  be  any  fossils  in  the  Collection  referable- 
to  this  genus.  Kemains  of  the  existing  Arctic  species,  Coitus 
uncinatus,  Eeinhardt,  have  been  recorded  from  nodules  in  Pleisto¬ 
cene  Clay,  Green’s  Creek,  Ottawa,  Canada  (J..  W.  Dawson,  Canad. 
llecord  Sci.  vol,  iv.  1890,  p.  86).  Detached  bones  of  the  existing 
Coitus  quadricornis^  Linn.,  var.  relicta,  Lilljeborg,  have  also  been 
identified  from  the  Pleistocene  of  Skattmanso,  Upland,  Sweden 
(A.  G.  Nathorst,  Geol.  Poren.  Stockholm  Porhandl.  vol.  xv.  1893, 
p.  569,  figs.  8,  9,  12,  13). 

The  names  Coitus  cry piotr emus,  divaricatus,  hypoceras,  and? 
pontifex  are  given  to  preopercula  supposed  to  represent  four  extinct 
species  from  Preshwater  Tertiary  deposits  in  Idaho  and  Oregon, 
U.S.A.  (E.  D.  Cope,  Proc.  Acad.  Nat.  Sci.  Philad.  1883,  pp.  162-164). 
Nothing  is  known  of  the  undescribed  Coitus  horridus  (J.  J.  Heckel, 
Neues  Jahrb.  1849,  p.  499)  from  Wieliczka,  Galicia. 

An  otolith  from  the  Lower  Tertiary  of  the  Jackson  Diver, 
Mississippi,  has  been  referred  to  a  member  of  this  family  under  the 
name  of  Otolithus  {Cottidarum)  sulcatus  (E.  Koken,  Zeitschr.  deutsch. 
geol.  Ges.  vol.  xl.  1888,  p.  287,  pi.  xviii.  fig.  12). 


Family  TRIGLID^. 

Suborbitals  enlarged  and  covering  cheek ;  mouth  terminal,  with 
minute  teeth.  Abdominal  vertebrae  with  transverse  processes  very 
short  or  absent.  Post-temporal  bone  fused  with  cranium,  and  supra- 
clavicle  displaced  backwards  so  that  the  post-temporal  and  clavicle 
are  in  contact.  Pectoral  fins  laterally  placed  and  expanded,  with 
pelvic  fins  directly  beneath ;  spinous  dorsal  less  extended  than  soft 
dorsal,  which  is  similar  to  the  spineless  anal.  Squamation  regular, 
and  no  bony  scutes  except  along  lateral  line.

There  appear  to  be  no  remains  of  members  of  this  family  among

The  so-QSiU3d  Gobius  leptosou/^uhT^a  macroactus  (D.  G.  Kram¬ 
berger,  Palaeontogr.  vol.  xxvi.  1879,  pp.  63-65,  pi.  xvi.  figs.  4,  5), 
from  the  Lower  Oligocene  of  Galicia,  are  too  imperfectly  known 
I  for  certain  reference  to  this  systematic  position.  The  same  remark 
applies  to  Gobius  microcephalus,  which  was  only  doubtfully  placed 
here  by  Agassiz  (Poiss.  Loss.  vol.  iv.  1839,  p.  204,  pi.  xxxiv.  fig.  2), 
and  is  probably  a  Blennioid  though  not  satisfactorily  determinable.

specimen : —

TRACHINID^. 


589 


Family  TRACHINIDJ?!. 

As  Gobiidse,  but  gill-opening  wide,  pelvic  fins  never  united,  and 
most  of  the  abdominal  vertebrae  without  transverse  processes. 

Small  fishes  living  at  the  bottom  on  nearly  all  coasts,  some¬ 
times  ranging  into  the  deep  sea.  There  are  no  extinct  genera  of 
importance. 


Genus  CALLIPTERYX,  Agassiz. 

[Poiss.  Foss.  vol.  iv.  1838,  p.  12.] 

Eye  apparently  lateral ;  teeth  minute  and  clustered.  Vertebrae 
10  in  the  abdominal,  14  in  the  caudal  region.  Dorsal  fins  con¬ 
tinuous,  the  anterior  portion  comprising  about  9  very  short  spines  ; 
anal  fin  less  extended  than  posterior  dorsal ;  caudal  fin  rounded. 
Scales  very  small  or  absent. 

An  extinct  genus  known  only  by  two  species  from  the  marine 
Tipper  Eocene  of  Italy.

stout,  finely  striated  spines,  then  a  more  slender  and  slightly  longer 
spine,  then  30  articulated  and  divided  rays,  most  of  which  are  at 
least  twice  as  long  as  the  spines  ;  anal  fin  with  one  or  two  feeble 
small  spines  and  20  articulated  and  divided  rays,  the  fin  terminating 
behind  opposite  the  end  of  the  dorsal.

BLOCHIID^. 


Genus  BLOCHIUS,  Volta. 
[Ittiolit.  Veronese,  1796,  p.  liii.] 


Eostrum  very  slender,  projecting  far  in  advance  of  the  mandible^ 
which  articulates  beneath  the  hinder  end  of  the  cranium  ;  rami  of 
mandible  probably  fused  at  symphysis ;  teeth  minute  or  absent. 
Vertebrae  about  12  in  the  abdominal,  12  in  the  caudal  region ;  the 
centra  much  elongated  and  constricted, imperfectly  ossified.  Pectoral 
fins  small ;  [pelvic  pair  supposed  to  be  present,  but,  if  so,  relatively 
small  and  jugular] ;  caudal  fin  slightly  forked.  Bony  scutes 
diamond-shaped,  slightly  overlapping,  completely  and  regularly 
covering  the  trunk  and  partly  extending  over  the  opercular  appa¬ 
ratus  and  cheeks ;  two  longitudinal  series  of  scutes  somewhat 
enlarged  on  each  flank. 

So  far  as  can  be  determined  from  the  fractured  specimens  in  the- 
Collection,  the  remarkably  elongated  rostrum  of  this  genus  bears 
much  resemblance  to  the  supposed  dermal  spines  from  the  Upper 
Eocene  named  Coeloi'hynclms  (see  Part  II.  p.  120).  When  suflci- 
ently  well-preserved  rostra  of  the  typical  Blocliiiis  are  available  for 
microscopical  examination,  it  will  be  interesting  to  compare  the 
structure  with  that  of  Coelorhynchus,  and  also  with  that  of  the 
apparently  Chimseroid  spines  from  the  Cretaceous  which  commonly 
bear  the  same  name.

much  further  forwards  than  the  base  of  the  rostrum. 
Small  scutes  are  seen  to  extend  over  the  opercular  appa¬ 
ratus  ;  and  the  ossified  sclerotic  is  partly  preserved.  The 
pectoral  fins  are  displaced  but  both  shown  as  indicated  in 
Agassiz’s  figure  ;  the  lowermost  exhibiting  three  of  its  basal 
bones  in  position.  Comparatively  small  and  delicate  rays 
in  front  of  the  pectorals  may  represent  pelvic  fins,  but  it 
is  uncertain  whether  these  are  not  merely  branchiostegal 
rays.  The  dorsal  fin-spines  have  the  appearance  of 
extending  forwards  over  the  head  merely  in  consequence 
of  the  displacement  of  parts  just  described.  The  depth  of 
the  abdominal  region  in  the  fossil  must  also  be  less  than 
was  actually  the  case  during  life.  Enniskillen  Coll. 

P.  4142.  More  imperfect  and  distorted  larger  specimen,  showing  the 
mandible  as  before,  and  the  parts  of  the  cranium  much 
scattered.  Immediately  in  front  of  the  frontals,  the 
fractured  base  of  the  rostrum  seems  to  consist  of  a  pair  of 
tubes  pressed  together  like  those  of  the  so-called  Coelo- 
rhy7iGhus.  A  longitudinal  series  of  rather  large  perforations 
penetrating  the  dense  armour  of  the  hinder  part  of  the  tail, 
appears  to  mark  the  course  of  the  lateral  line. 

Enniskillen  Coll. 

19940.  Eine  small  fish,  distorted  like  the  preceding  specimens  at 
the  back  of  the  head  and  in  the  abdominal  region.  The 
slender  mandible  is  seen  to  extend  not  much  further 
forwards  than  the  base  of  the  rostrum ;  and  the  delicate 
suspensorium  is  displaced  between  it  and  the  cranium. 
Small  scutes  extend  over  the  triangular  operculum  and 
perhaps  over  part  of  the  cheek.  The  haemal  arches  of  most 
of  the  vertebrae  are  observable,  and  used  in  the  accom¬ 
panying  restoration  (fig.  22).  The  median  fins  and  dermal 
scutes  are  also  well  preserved  ;  the  enlarged  flank-scutes

Family  BLENNIID^. 

%/ 

Elongated  fishes  with  stout  caudal  pedicle ;  snout  not  produced. 
Most  of  the  abdominal  vertebrse  with  downwardly  directed  transverse 
processes  bearing  the  small  ribs.  Dorsal  fin  occupying  nearly  the 
whole  of  tbe  back,  often  subdivided  ;  anal  fin  also  much  extended  ; 
caudal  fin  rounded  or  tapering.  Scales  small  or  absent,  and  no  bony 
scutes. 

Marine  fishes  living  at  the  bottom  near  almost  all  coasts,  and  a 
few  freshwater  species.  Scarcely  known  among  fossils,  but  repre¬ 
sented  by  at  least  one  extinct  genus  allied  to  Cristicejgs^  and  perhaps 
by  another  {Oncolepis)  of  doubtful  affinities.

Genus  PTERYGOCEPHALUS,  Agassiz. 

[Poiss.  Foss.  vol.  iv.  1839,  p.  190.] 

Head  short  and  orbit  very  large  ;  mouth  small,  with  conical  teeth. 
Vertebrae  about  10  in  the  abdominal,  14  in  the  caudal  region.  Dorsal 
fin  very  deep,  the  foremost  large  spine  displaced  forwards  above  the 
head  but  the  fin  otherwise  continuous.  Squamation  well  developed 
and  continuous,  each  scale  with  a  longitudinal  keel,  and  the  keels 
forming  regular  lines  along  the  trunk.

As  noticed  by  Agassiz,  the  following  fragmentary  specimens  bear 
some  resemblance  to  the  skull  of  the  existing  genus  Anarrliiclias,  but 
they  exhibit  too  many  differences  to  be  definitely  ascribed  to  the

Suborder  X.  ANACANTHINI. 

Vertebral  centra  always  complete  constricted  cylinders,  none 
coalesced.  Supraoccipital  extending  forwards  between  the  reduced 
parietals ,  S(][uamosal  rudimentary  and  fused  with  the  large  pterotic  j 
mandible  simple,  each  ramus  consisting  only  of  two  elements 
(dentary  and  articulo-angular).  Xo  spinous  fin-rays.  Pectoral  arch 
suspended  from  the  cranium ;  precoracoid  arch  absent ;  infra- 
clavicular  plates  absent ;  pectoral  fin  with  not  more  than  four  or 
five  basals.  Pelvic  fins,  when  present,  thoracic  or  jugular.  In  the 
living  forms  : — air-bladder,  when  present,  not  connected  with  the 
oesophagus  by  a  duct  in  the  adult  (physoclistous)  j  optic  nerves 
decussating  ’  intestine  without  spiral  valve  ^  reproductive  organs

small.  Both  paired  fins  present,  usually  well-developed.  Dorsal 
fin  occupying  nearly  the  whole  of  the  back,  simple  or  more  or  less 
subdivided  into  two  or  three  parts  ;  one  or  two  anal  fins  ;  caudal 
fin  separate,  or  if  united  with  other  median  fins,  the  dorsal  with  a 
separate  anterior  portion.  Scales  small  and  cycloid.  In  the  recent 
forms : — air-bladder  and  pyloric  appendages  usually  present ;  pseudo- 
branchise  absent,  or  glandular  and  rudimentary. 

This  family  dates  back  to  the  Upper  Eocene,  but  only  one  extinct 
genus  is  recognisable.  The  “  cod-fishes  ”  and  their  allies  of  the 
present  day  chiefly  inhabit  the  seas  of  the  north  temperate  and 
arctic  regions,  often  descending  to  great  depths.  Only  one  genus 
{Lota,  Cuvier)  occurs  in  freshwaters.

head  with  opercular  apparatus  probably  exceeding  twice  the  maxi¬ 
mum  depth  of  the  trunk  and  contained  about  tvfice  in  the  length 
from  the  pectoral  arch  to  the  base  of  the  caudal  fin.  Yertebrm 
approximately  45  in  number.  Pectoral  fins  with  about  17  rays. 
Anterior  portion  of  dorsal  fin  with  about  13  rays,  the  middle 
portion  with  16  more  closely  arranged  rays  ;  anterior  portion  of 
anal  fin  with  18  rays.  ^  ^

Family  PLEURONECTIDA:.A.'’»?"f'r'/“^  ' 

A  K  TCIC  .  6  S  • 

Trunk  deepened,  much  laterally  compres’sed  and  fiattened,  the 
fishes  always  resting  on  one  side  when  adult.  Skull  unsym- 
metrically  developed,  and  both  eyes  in  the  adult  situated  on  the 
one  side  which  is  always  coloured  and  turned  upwards  when  at  rest. 
Premaxilla  excluding  maxilla  from  gape.  Abdominal  region  very 
short.  Paired  fins  small,  often  unsymmetrically  developed,  and  one 
or  more  sometimes  absent.  Dorsal  and  anal  fins  much  extended, 
not  subdivided.  In  the  recent  forms  : — gills  four  ;  pseudobranchise 
well  developed  ;  air-bladder  absent. 

This  family  dates  back  to  the  Upper  Eocene,  but  no  extinct 
genera  are  recognisable.  In  existing  seas  its  range  is  cosmopolitan, 
and  a  few  forms  live  in  freshwater.

Mouth  wide,  the  jaws  and  dentition  being  nearly  equally 
developed  on  both  sides  ;  a  narrow  band  of  villiform  teeth,  without 
canines,  on  the  margin  of  the  juws  ;  equally  small  teeth  also  on  the 
vomer  but  not  on  the  palatines.  Eyes  on  the  left  side.  Gill-rakers 
well-developed,  lanceolate  ;  seven  branchiostegal  rays.  Abdominal 
vertebrae  with  broad  transverse  processes,  and  very  small  delicate 
ribs ;  haemal  spines  at  base  of  caudal  fin  somewhat  expanded,  not 
fused  together.  Both  pairs  of  fins  present,  usually  unsymmetrically 
developed ;  dorsal  fin  arising  on  the  snout ;  caudal  fin  separate,

Some  of  these  characters  cannot  be  observed  in  the  fossils,  which 
are  thus  only  provisionally  determined.  The  existing  species 
inhabit  the  North  Atlantic  and  Mediterranean.

Foss.  Agr.  Veron.  (1859),  p.  36,  pi.  xiii.  fig.  1. 

Type.  Nearly  complete  fish  ;  Palseontological  Museum,  Munich. 

A  very  small  species,  attaining  a  length  of  about  0*1.  Length 
of  head  with  opercular  apparatus  contained  two  and  a  half  times 
in  the  length  from  the  pectoral  arch  to  the  base  of  the  caudal  fin  ; 
maximum  depth  of  trunk  about  four  fifths  of  latter  measure. 
Vertebrae  11  or  12  in  the  abdominal,  20  in  the  caudal  region. 
Dorsal  and  anal  fins  deepest  in  their  middle  portion,  the  former 
with  about  65,  the  latter  with  about  45  rays ;  both  these  fins 
terminating  very  close  to  the  caudal,  which  comprises  17  rays. 
Small  scales  well  developed,  apparently  cycloid. 

Form.  Log.  Upper  Eocene  :  N.  Italy. 

1657.  Fine  specimen,  0*06  in  length,  in  counterpart  ;  Monte 
Bolca.  The  head  is  imperfect,  but  the  trunk  and  median 
fins  are  well  displayed.  Appearances  suggest  a  dense 
squamation  of  small  cycloid  scales. 

Presented  by  Chambers  Hall,  Esq. 

P.  3971.  Another  good  specimen  broken  and  distorted  in  the 
caudal  region ;  Monte  Bolca.  The  dorsal  fin  is  shown 
arising  on  the  snout.  The  head  and  opercular  apparatus 
are  tolerably  well  preserved  ;  and  the  delicate  pectoral  fin 
is  seen.  Some  of  the  abdominal  vertebrae  exhibit  their 
large  transverse  processes  ;  and  there  are  remains  of  the 
small,  slender  ribs.  EnnisTcillen  Coll. 

Dermal  tubercles  resembling  those  of  the  existing  Rhombus 
maximus,  Cuv.,  are  recorded  from  the  Lower  Pliocene  of  Orciano, 
Tuscany,  under  the  name  of  Rhombus  gentiluomoi  by  B.  Lawley, 
Nuovi  Studi  Pesci,  etc.,  CoUine  Toscane  (1876),  p.  82.^

Mouth  small  and  unsymmetrical,  twisted  round  to  the  left  (blind) 
side  :  teeth  minute  and  villiform,  confined  to  the  left  margin  of  the 
jaws.  Eyes  on  the  right  side,  the  upper  being  more  or  less  in 
advance  of  the  lower.  Abdominal  vertebrae  with  very  small  trans¬ 
verse  processes  and  rudimentar}^  ribs,  but  most  of  them  with  long 
and  robust  haemapophyses.  Both  pairs  of  fins  usually  represented, 
but  often  unsymmetrical  and  one  sometimes  Mbsent ;  dorsal  fin 
arising  on  the  snout ;  caudal  fin  separate,  roundi'd  behind.  Scales 
very  small,  antero-posteriorly  elongated,  deeply  overlapping,  and 
ctenoid. 

Existing  species  occur  in  all  temperate  and  tropcal  seas,  and  a 
few  inhabit  freshwaters.

ACTTNOPTERYGTT. 


Type.  Imperfect  fish. 

A  very  small  species,  attaining  a  length  of  about  0*08.  Length 
of  head  with  opercular  apparatus  contained  four  and  a  half  times, 
maximum  depth  of  trunk  two  and  a  half  times  in  the  total  length 
to  the  base  of  the  caudal  fin.  Abdominal  vertebrae  9,  caudal 
vertebrae  24  in  number.  Pectoral  and  pelvic  fins  present.  Dorsal 
margin  nearly  straight  in  the  middle,  the  fin  comprising  about  50 
to  55  rays  ;  anal  fin  with  about  40  rays.  Sqiiamation  dense. 

The  otoliths  of  this  species  are  described  by  von  IMeyer,  loc.  cit. 
1856. 

Form.  Loc.  Lower  Pliocene  :  ^Yurtemberg. 

36179,  36578.  Fine  specimen  in  counterpart,  displaying  the 
characters  noted  in  the  specific  diagnosis  ;  Unterkirchberg 
near  Ulm.  The  vertebral  centra  are  broken,  and  the 
edges  of  the  median  fins  are  imperfect.  The  characteristic 
haemapophyses  of  the  abdominal  vertebrae  are  shown,  and 
one  of  the  delicate  pectoral  fins,  as  also  one  of  the 
small  pelvic  fins,  is  preserved.  Purchased,  1861-62. 

36178.  More  imperfect  large  specimen;  Unterkirchberg. 

Purchased,  1861. 

35749.  Smaller  specimen,  with  well-preserved  caudal  fin,  which 
comprises  18  rays  ;  Unterkirchberg.  Purchased,  1860. 

The  two  undermentioned  imperfect  specimens  represent  a  form 
essentially  identical  with  S.  hirchhergana,  but  exhibiting  a  more 
arched  hack  and  other  minor  differences  which  are  considered  to 
indicate  a  distinct  species  named  S.  antiqua  by  H.  von  Meyer, 
Palaeontogr.  vol.  ii.  (1851),  p  103,  pi.  xvii.  figs.  4-7,  and  ihid. 
vol.  vi.  (1856),  p.  26,  pi.  i.  figs.  4,  5. 

P.  3972.  Large  distorted  specimen  ;  Unterkirchberg. 

Ennislillen  Coll.
